16 Risks of ultraviolet exposure Introduction Caution: This instrument is used in conjunction with ultraviolet light. Exposure to these radiations, even reflected or diffused, can result in serious, and sometimes irreversible, eye and skin injuries. Overexposure to ultraviolet rays threatens human health by causing: Immediate painful sunburn Skin cancer Eye damage Immune-system suppression Premature aging Do not aim the UV light at anyone. Do not look directly into the light. Always wear protective goggles, full-face shield and skin protection clothing and gloves when using the light source. Light is subdivided into visible light, ranging from 400 nm (violet) to 700 nm (red); longer infrared, above red or > 700nm, also called heat; and shorter ultraviolet radiation (UVR), below violet or < 400nm. UVR is further subdivided into UV-A or near-uv ( nm), also called black (invisible) light; UV-B or mid-uv ( nm), which is more skin penetrating; and UV-C or far-uv (< 290 nm). Health effects of exposure to UV light are familiar to anyone who has had sunburn. However, the UV light level around some UV equipment greatly exceeds the level found in nature. Acute (short-term) effects include redness or ulceration of the skin. At high levels of exposure, these burns can be serious. For chronic exposures, there is also a cumulative risk of harm. This risk depends upon the amount of exposure during your lifetime. The long-term risks for large cumulative exposure include premature aging of the skin, wrinkles and, most seriously, skin cancer and cataract. Damage to vision is likely following exposure to high-intensity UV radiation. In adults, more than 99% of UV radiation is absorbed by the anterior structures of the eye. UVR can contribute to the development of age-related cataract, pterygium, photodermatitis, and cancer of the skin around the eye. It may also contribute to age-related macular degeneration. Like the skin, the covering of the eye or the cornea, is epithelial tissue. The danger to the eye is enhanced by the fact that light can enter from all angles around the eye and not only in the direction of vision. This is especially true while working in a dark environment, as the pupil is wide open. The 0-8

17 Introduction lens can also be damaged, but because the cornea acts as a filter, the chances are reduced. This should not lessen the concern over lens damage however, because cataracts are the direct result of lens damage. Burns to the eyes are usually more painful and serious than a burn to the skin. Make sure your eye protection is appropriate for this work. NORMAL EYEGLASSES OR CONTACTS OFFER VERY LIMITED PROTECTION! Training Caution: UV exposures are not immediately felt. The user may not realize the hazard until it is too late and the damage is done. For the use of UV sources, new users must be trained by another member of the laboratory who, in the opinion of the member of staff in charge of the department, is sufficiently competent to give instruction on the correct procedure. Newly trained users should be overseen for some time by a competent person. 0-9

18 Additional risks of xenon lamps Introduction Among the dangers associated with xenon lamps are: Burns caused by contact with a hot xenon lamp. Fire ignited by hot xenon lamp. Warning: Xenon lamps are dangerous. Please read the following precautions. Interaction of other nearby chemicals with intense ultraviolet, visible, or infrared radiation. Damage caused to apparatus placed close to the xenon lamp. Explosion or mechanical failure of the xenon lamp. Visible radiation Any very bright visible light source will cause a human aversion response: we either blink or turn our head away. Although we may see a retinal afterimage (which can last for several minutes), the aversion response time (about 0.25 seconds) normally protects our vision. This aversion response should be trusted and obeyed. NEVER STARE AT ANY BRIGHT LIGHT-SOURCE FOR AN EXTENDED PERIOD. Overriding the aversion response by forcing yourself to look at a bright light-source may result in permanent injury to the retina. This type of injury can occur during a single prolonged exposure. Excessive exposure to visible light can result in skin and eye damage. Visible light sources that are not bright enough to cause retinal burns are not necessarily safe to view for an extended period. In fact, any sufficiently bright visible light source viewed for an extended period will eventually cause degradation of both night and color vision. Appropriate protective filters are needed for any light source that causes viewing discomfort when viewed for an extended period of time. For these reasons, prolonged viewing of bright light sources should be limited by the use of appropriate filters. The blue-light wavelengths ( nm) present a unique hazard to the retina by causing photochemical effects similar to those found in UV-radiation exposure. Infrared radiation Infrared (or heat) radiation is defined as having a wavelength between 780 nm and 1 mm. Specific biological effectiveness bands have been defined by the CIE (Commission Internationale de l Eclairage or International Commission on Illumination) as follows: IR-A (near IR) ( nm) IR-B (mid IR) ( nm) IR-C (far IR) (3000 nm 1 mm) 0-10

19 Introduction The skin and eyes absorb infrared radiation (IR) as heat. Workers normally notice excessive exposure through heat sensation and pain. Infrared radiation in the IR-A that enters the human eye will reach (and can be focused upon) the sensitive cells of the retina. For high irradiance sources in the IR-A, the retina is the part of the eye that is at risk. For sources in the IR-B and IR-C, both the skin and the cornea may be at risk from flash burns. In addition, the heat deposited in the cornea may be conducted to the lens of the eye. This heating of the lens is believed to be the cause of so called glassblowers cataracts because the heat transfer may cause clouding of the lens. Retinal IR Hazards (780 to 1400 nm): possible retinal lesions from acute high irradiance exposures to small dimension sources. Lens IR Hazards (1400 to 1900 nm): possible cataract induction from chronic lower irradiance exposures. Corneal IR Hazards (1900 nm to 1 mm): possible flashburns from acute high irradiance exposures. Who is likely to be injured? The user and anyone exposed to the radiation or xenon lamp shards as a result of faulty procedures. Injuries may be slight to severe. 0-11

20 CE compliance statement Introduction The ihr-series spectrometers are tested for compliance with both the EMC Directive 89/336/EEC and the Low Voltage Directive for Safety 73/23/EEC, and bear the international CE mark as indication of this compliance. HORIBA Instruments Incorporated guarantees the product line s CE compliance only when original HORIBA Instruments Incorporated supplied parts are used.

21 Requirements & Installation 1: Requirements & Installation Safety-training requirements Every user of the ihr-series spectrometers must know general and specific safety procedures before operating the instrument. For example, proper training includes (but is not limited to): Understanding the risks of exposure to ultraviolet, visible, and infrared light, and how to avoid unsafe exposures to these types of radiation Safe handling for all chemicals and other samples used in the instrument Safety-training may be purchased from HORIBA Scientific. Contact your Sales Representative or the Service Department for details. 1-1

22 Surface requirements Requirements & Installation A sturdy table- or bench-top Surface must hold 90 kg (200 lbs.). Surface should be about (69 cm 183 cm) to hold spectrometer, computer, and accessories comfortably. Overhead clearance should be at least 36" (91 cm). 1-2

23 Environmental requirements Recommended operating temperature range C (68 86 F) Requirements & Installation Note: For optimum performance, keep the ambient temperature between 20 and 30 C. Maximum temperature fluctuation ± 2 C around average ambient temperature Ambient relative humidity < 75% Caution: Excessive humidity can damage the optics. Low levels of dust, smoke, and corrosive chemicals No special ventilation 1-3

24 Electrical requirements Requirements & Installation The ihr operates from a 24 V DC input. This is provided by the universal input (100 V 240 V, 1.6 A), 24 V 2.1 A output external brick power supply (J964007) supplied with the instrument. The power supply is plugged into a standard wall outlet (mains) using a standard three-conductor power cord (J98015 for 110 V or J98020 for 220 V). Caution: HORIBA Scientific is not liable for damage from line surges and voltage fluctuations. A surge protector is strongly recommended for minor power fluctuations. For more severe voltage variations, use a generator or uninterruptible power supply. Improper line voltages can damage the equipment severely. Warning: The ihr spectrometer is equipped with a three-conductor power cord that is connected to the system frame (earth) ground. This ground provides a return path for fault current from equipment malfunction or external faults. For all instruments, ground continuity is required for safe operation. Any discontinuity in the ground line can make the instrument unsafe for use. Do not operate this system from an ungrounded source. 1-4

25 Computer requirements Requirements & Installation The ihr provides a USB interface with a built in USB 2.0 hub for communications with a host computer. It also provides an additional USB port for connecting to a downstream USB device. The ihr is controlled by HORIBA Scientific s Spectrometer Utilities program, SynerJY data acquisition software, or with LabVIEW VIs. Computer requirements for the ihr are: One free USB port for USB communications DVD drive Meets the requirements specified by the user s operating system See the User s Guide for SynerJY Software Version 3.5 for computer software and hardware requirements, such as Windows 2000, Vista, XP or 7 (32-bit compatibility mode); PC is typically configured with 3 or more USB ports; 1 GB RAM, minimum; 1GB available hard-disk space 1-5

26 Safety requirements Requirements & Installation Observe the following precautions to prevent possible damage to the ihr: Do not connect or disconnect any cables to or from the ihr when the instrument is powered on. Keep the grating in a closed instrument or storage container at all times. Do not touch the grating surface. Caution: Never touch the grating surface not even with lens tissue. Damage can easily occur and degrade performance. Such damage is not covered by warranty. Fingerprints on a grating surface cause permanent damage. If fingerprints get on the grating surface, do not attempt to clean them. 1-6

27 General maintenance requirements Requirements & Installation We recommend periodically cleaning the external surfaces of the ihr by wiping them down with a clean, damp cloth. Only perform this procedure on external surfaces. Do not use any other solvents, soaps, or abrasives when cleaning, for these products can damage surface finishes. While the mirrors and gratings of the ihr require no routine maintenance, exercise care to prevent damage to their surfaces. Should dust particles accumulate on the grating surface, it is better to leave them rather than risk possible surface damage caused by cleaning. 1-7

28 Unpacking and installation Introduction Requirements & Installation Before use, set up your ihr spectrometer and all accompanying components. The installation of your HORIBA Scientific spectrometer and application software has several separate stages that must be completed in the order below for the system to operate properly.

38 ihr operation modes Initial Power-up & Operation The ihr is extremely versatile, and can be customized to accommodate most applications. Selection of entrance and exit ports, gratings, and spectroscopic accessories allows you to tailor the ihr specifically to your experiment. The spectrometer is controllable via the accompanying USB Spectrometer Control Software (CSW-USB- SUPPORT-MONO) as well as with SynerJY, SynerJY Software Development Kit, or LabVIEW VIs. Spectrograph operation Figure 2-1: Options for ihr entrance and exit ports ihr units equipped to operate as spectrographs have at least one entrance slit and a CCD flange. Options for a side entrance and side exit are also available. When taking measurements with a spectrograph, the light to be analyzed is diffracted by the grating and dispersed across the exit focal plane. An array detector such as a 2D CCD or linear InGaAs array mounted at the exit is used to measure, or take a snapshot of, a range of wavelengths. The grating position for a particular wavelength range is identified by the center wavelength position. Data for a 2D detector may be recorded for each individual pixel, as an image, or with the vertical pixels in each pixel column summed as a spectrum. 2-2

39 Monochromator operation Initial Power-up & Operation ihr units equipped to operate as monochromators are configured with an entrance and an exit slit. Options are available for a side exit slit and a side entrance slit. As the name suggests, a monochromator is used to select a single wavelength of light. Here are four typical applications for the ihr when configured as a monochromator: Scanning monochromator Tunable light source Spectral filter Fixed wavelength measurement The instrument can be used to measure the spectral output of emitted light. The light can come from the sun, a laser diode, a glow discharge, etc. With a broadband light-source directly coupled to the entrance slit, the ihr can provide a specific bandpass (range of wavelengths) at the exit. Changing the slit-width varies the spectral bandpass. The ihr can be used to select a particular bandpass of light, at different user-selected wavelengths. The ihr, when set to a fixed wavelength and bandpass with a single-channel detector coupled to the exit slit, can monitor variations in an incoming light-signal, such as laser power. 2-3

41 External Filter Wheel Shutter Connector Initial Power-up & Operation Establishes communications between a HORIBA Scientific external filter wheel and the ihr. The External Filter Wheel requires cable J Provides the user the option of connecting a shutter cable to the ihr via a BNC connection. 2-5

42 Drive operation Initial Power-up & Operation The ihr uses a precision worm-wheel gear drive mechanism under stepper-motor control which enables a user to drive precisely to a given wavelength or scan over a wavelength range. The drive has a scan range of 0 nm to 1500 nm (for a 1200 gr/mm grating). The wavelength resolution of the drive is user selectable with a minimum step size of nm (with a 1200 gr/mm grating). The drive must be initialized upon powering up. The initialization process precisely homes the drive mechanism, allowing for very accurate and repeatable wavelength settings. The drive will hold position indefinitely as long as the unit is powered up. If the system is powered down, there can be a small shift in drive position. The drive requires no backlash correction when moving in the direction of increasing wavelength. We therefore recommend that users scan from lower to higher wavelengths. When the system is directed to move from a higher wavelength to a lower wavelength, an automatic backlash correction is performed. Although the wavelength accuracy and precision of the drive is unaffected, the backlash operation adds additional time to the scan. When moving from lower to higher wavelength, the drive scan speed is approximately 160 nm/s. 2-6

43 Triple-grating turret Initial Power-up & Operation The ihr s unique turret design allows it to maintain on-axis grating rotation during scanning, delivering superior optical performance. The triple grating turret supports three gratings; rotation is controlled by a single stepper-motor. Grating selection is software-controlled. The operation for changing the grating is automated and takes approximately 30 seconds per grating. Additional turrets may be purchased for the ihr320 and ihr550. The grating turret is kinematically mounted, allowing the user to interchange turrets without the need for realignment. 2-7

44 Configuring hardware Initial Power-up & Operation If you received your copy of USB Spectrometer Utilities with your ihr, the software has already been preconfigured to find and control your spectrometer. Once the spectrometer is identified, you must create a hardware configuration. 1 The USB Device Selection dialog box appears the first time the spectrometer is used, indicating that an exact hardware match has not been found. The window lists all of the compatible hardware, i.e., spectrometers, attached to your computer. Highlight the hardware description that matches your ihr and click the OK button. If more than one ihr is listed, chose the correct one based on serial number. 2 To configure using USB Spectrometer Utilities software, select Start>Programs>Jobin Yvon>USBSpectrometerControl. The USB Spectrometer Control program allows you to initialize the instrument as well as enter or change the wavelength position, mirror position, and slitwidths. It also allows you to configure and change the filter-wheel position if your ihr is equipped with an internal filter wheel. If using SynerJY software, see the Hardware Configuration topics located in the SynerJY Installation Guide and Help file. Note: The USB Spectrometer Control program only allows you to configure your spectrometer (and optional internal filter wheel), and is not equipped to create hardware configurations for detectors and accessories. You must use SynerJY or the software provided with your detector to create a system configuration. 3 If adding a new spectrometer, select the appropriate model from the Choose Spectrometer drop-down list and click the Initialize button; proceed to Step

49 Controlling the ihr Initial Power-up & Operation The USB Spectrometer Utilities CD supplied with the ihr contains two programs that can be used together to control the spectrometer: The USB Spectrometer Control program allows you to enter or change the wavelength position, mirror position, control slits, and filter-wheel position (if your ihr is equipped with an internal filter wheel). The USB Mono Config program allows you to select the appropriate grating as well as change the offset. Note: USB Spectrometer Utilities programs only allow you to control your spectrometer (and optional internal filter wheel) and are not equipped to control detectors and accessories. You must use SynerJY or the software provided with your detector to control additional system components. USB Spectrometer Control 1 Make sure your hardware is configured. Select Start>Programs>Jobin Yvon>USBSpectrometerControl. 2 Set the fields to the desired settings. The Wavelength Control area moves the spectrometer to the specified wavelength (in nm), as an incremental increase or decrease. The Slits area adjusts the slit-width (in mm). Slits options are: Front Entrance, Front Exit, Side Entrance, and Side Exit. Click on fields, and enter the appropriate values. Figure 2-8: USB Spectrometer Control program 2-13

Calibrating the grating using USB Spectrometer Utilities The grating calibration procedure serves as an initial check, before running an experiment, that your system s monochromator is properly calibrated and aligned. Note: You must use the software provided with your detector (in conjunction with USB Spectrometer Utilities) to collect a spectrum and determine the peak-pixel position corresponding to the reference peak. If using SynerJY, see the Monochromator Calibration procedure of the Help file. 1 Set up a calibration source, such as a mercury lamp, on the front entrance slit of the ihr. 2 Make sure your detector is mounted onto the exit port. 3 Select Start>Programs>Jobin Yvon>USBSpectrometerControl. 4 Set the slit-width to a minimum (~0.01 mm) and manually adjust the height limiter to 1 mm. 5 Set the Position to a reference wavelength value (such as a mercury line at nm). 2-15

For multi-channel detectors (CCD, array) a b c d Set the x-axis to display in Pixels. Collect a spectrum and note the peak-pixel position corresponding to the reference peak. If the ihr is calibrated correctly, the peak-pixel position should be at the center pixel of the CCD chip (for example, for a 1024-pixel-wide CCD chip, the peak should appear at pixel 512). If the peak does not appear at the central pixel, change the center wavelength position until the peak appears in the center of the chip. Record the observed position of the reference peak. For single-channel detectors (PMT, DSS) a b Scan the grating in the region of the reference peak until the detector reads the maximum signal. Record the observed position of the reference peak. 7 Select the Gratings tab, then select the Grating # you are calibrating from the dropdown list. 8 Click the Calibrate Grating button.

Figure 2-9: WaveLengths window 2-17

54 Changing gratings Introduction Initial Power-up & Operation Although a single-grating turret is included in the basic configuration for an ihr320 or ihr550 spectrometer, you can order an additional grating turret (or turrets) at the time of your initial spectrometer purchase. In order for the instrument to work properly and correctly identify which turret is used, a separate firmware configuration and a separate software configuration are both required for each grating turret. When changing from one grating turret to another, you must load the appropriate firmware using the USB Spectrometer Utilities software according to the procedure described below. If you ordered a new ihr spectrometer with two grating turrets, the firmware for turret 1 is preloaded. If you purchased SynerJY software, the firmware files for Turret 1 and Turret 2 are burned onto the SynerJY installation disk, in addition to the SynerJY software configurations for Turret 1 and Turret 2. There are two options for the ihr chassis: With a circular port on top for changing gratings Without a circular port for changing gratings. If you have the option with no port, you will have to remove the top of the ihr case, and take extra care not to touch or damage the internal optics. Caution: Never touch the face of any grating or optics. We recommend using lint-free cotton gloves or powder-free nitrile gloves. Procedure 1 Insert the SynerJY disk into the DVD drive of your host computer. 2 Navigate to the Configurations folder on the SynerJY CD, and copy this folder to your host computer s desktop. 3 Install USB Spectrometer Utilities software according to the procedure on page 1-14 of this manual. 2-18

55 Initial Power-up & Operation 4 Remove Turret 1, put it in the appropriate storage container, and replace it with Turret 2 as shown on pages 1-11 and 1-12 of this manual. 5 Open the USB SpectrometerConfig utility program. This program allows you to configure the spectrometer firmware to accept the new gratings on Turret 2. The JYUSBMonoConfig window appears: 6 Click the Load From button. The Open window appears: 2-19

56 Initial Power-up & Operation 7 Navigate to the Configurations folder on your host computer s desktop, where you see two files named Turret 1 FirmWare Turret 2 FirmWare 8 Choose the appropriate firmware file (in this case Turret 2 FirmWare) and click the Open button. The Open window closes when the file loads. 9 Click the Write button, wait until the process is finished, then exit the program by clicking the red X in the upper right-hand corner. 2-20

57 Initial Power-up & Operation 10 Cycle the power on the ihr spectrometer. 11 Open SynerJY software, and select the configuration for Turret 2. To load the configurations for Turret 1 and Turret 2, follow the instructions in the SynerJY User s Guide on page 17, but select Load Factory Configuration in Step 4. Follow the prompts from the wizard, and select the correct SynerJY configuration from the Configurations folder now on the host computer s desktop. A typical file name is ConfigTurret2.jyc. 12 To revert back to Turret 1, follow the same procedure, but this time load the firmware for Turret 1, and select the SynerJY configuration for Turret

58 Slit adjustments Introduction Initial Power-up & Operation The slits of the ihr are fully automated. The width of the slit opening is controlled via software. Having the proper slit-width is critical, for it directly affects the throughput and wavelength resolution of the system. The slit-height also has an effect on resolution and throughput, although to a lesser extent. Slit-height is manually adjusted by a height limiter. See Chapter 5: System Performance for a more complete discussion of this topic. Automated slits The motorized, adjustable slits of the ihr are controlled remotely by computer. Slit width is continuously adjustable from 0 mm to 2 mm or 0 mm to 7 mm (optional). The height limiter controls the slit height and has three settings: closed (0 mm), 1 mm, and open (15 mm). The detents of the actuator are used as a guide for setting the height limiter. To open the height limiter completely, pull the actuator out until it stops. For a 1 mm opening, push the actuator to the first detent. To close the height limiter, push the actuator in until it stops. Closing the height limiter provides a useful way to block the input light in order to take a dark-level reading. Height limiter set to 1 mm via actuator Figure 2-10: Photograph of height-limiter Figure 2-11: Diagram of height-limiter and actuator 2-22

59 Initial Power-up & Operation Operation with dual entrance and exit ports The ihr offers optional configurations with two entrance ports and two exit ports. The exit ports can be equipped with either an automatic slit or a CCD flange. The addition of a second exit port allows for mounting two different detectors. Spectral output is switched from the front exit port to the side exit port via a computer-controlled swing mirror. Similarly, equipping the system with dual entrance ports allows for the mounting of two optical inputs which are also selectable via software. 2-23

60 CCD focus and rotation adjustment Initial Power-up & Operation The ihr provides mechanisms for precise adjustment of the focus and rotational alignment of a CCD camera. The adjustments consist of the CCD focus wheel, the focus-lock set screw, the CCD rotation adjustment screw, and the CCD flange lock. Note: For installation of a HORIBA Scientific CCD or array detector delivered with an ihr spectrograph, see the Installation of the CCD Camera section of Chapter 6. 1 Using a 2.5 mm Allen key, loosen the M3 cap head screw on the flange lock by turning the Allen key counter-clockwise (#1 on the drawing). This screw is accessed through the flange lock hole in the side of the unit. Note that when the flange lock is loose, the CCD flange is free to slide in and out of the unit. The thick side of the wedge is on the right. Imaging flange (MAI-II for ihr320, or MAI-I5I for ihr550). Figure 2-12: Attaching imaging flange MAI to the ihr 2 Using a 2 mm Allen key, remove the nine M3 button head screws which secure the top cover 2-24

61 Initial Power-up & Operation of the unit, and remove the top cover (#2 on the drawing). 3 Using a 1.5 mm Allen key, loosen the focus lock set screw (M3) (#3 on the drawing). 4 Replace the top cover. The CCD focus wheel and rotation adjustment screw are free to move. The CCD focus wheel, touching the inside face of the CCD flange, acts as a focus stop for the CCD flange. The CCD rotation adjustment screw, touching the pin on the CCD flange, acts as a rotation stop for the CCD flange. 5 To adjust the focus of the CCD camera, rotate the focus wheel with your fingers to drive the CCD flange out from the body. To bring the camera focus in, it is necessary to hold the camera against the wheel while rotating the focus wheel. 6 To adjust the rotation of the CCD camera, insert a 1.5 mm Allen key into the hole in the side of the unit to engage the CCD rotation adjustment set screw. Turning the screw into the body (clockwise) pushes against the pin on the CCD flange rotating the camera. To rotate in the opposite direction, turn the camera against the rotation adjustment screw while turning the screw counterclockwise. 7 When the focus and rotation of the camera are properly set, tighten the flange lock to clamp the CCD flange in position. 8 The focus wheel may now be locked in its current position by removing the top cover and tightening the focus lock set screw. Unless the spectrometer is being moved from place to place, it is not mandatory to lock the focus wheel. If it is necessary to remove the CCD for some reason, simply loosen the flange lock set screw and remove the CCD. This Quick-Align CCD adapter mechanism allows easy replacement of the CCD with minimal realignment. 2-25

62 Initial Power-up & Operation Initial start-up 1 Check that all system cables to and from the ihr are properly connected. 2 Make sure that all software has been installed before the unit is turned on. 3 Verify that the unit, computer, and any additional supporting equipment are connected properly to AC input power (mains). 4 Set the power switch on the back of the unit to the ON ( I symbol) position. The computer recognizes that a new USB device has been started up and is connected to the computer. The New Found Hardware Wizard window opens. 5 Click the Next button. As the ihr software is loaded, a warning that the software has not passed Windows Logo Testing appears. All HORIBA Scientific recommended software has been fully checked for compatibility issues and will not interfere with the correct operation of your system. 6 Click the Continue Anyway button. 7 When the software installation Figure 2-13: Found New Hardware Wizard Figure 2-14: Windows Logo Testing warning 2-26

65 3 : System Performance System Performance Diffraction-grating groove density and system performance The ihr320 and ihr550 have been designed to accommodate a wide range of interchangeable diffraction gratings. The choice of gratings provides the single most important means of tailoring the performance of the ihr to your specific application. The grating tables below show how the groove density of the grating affects some important performance characteristics. Table 3-1: Grating Table for the ihr320 (at 500 nm) Groove Density (grooves/mm) Typical Spectral Dispersion (nm/mm)** Typical Array Resolution (nm)* Typical Spectral Coverage (nm)* Mechanical Scan Range (nm)* Recommended Scan Range (nm) nm nm nm nm nm nm nm Table 3-2: Grating Table for the ihr550 (at 500 nm) Groove Density (grooves/mm) Typical Spectral Dispersion (nm/mm)** Typical Array Resolution (nm)* Typical Spectral Coverage (nm)* Mechanical Scan Range (nm)* Recommended Scan Range (nm) nm nm nm nm nm nm nm *These values refer to typical parameters at 500 nm for a format CCD with 26 µm pixels, therefore do not match the instrument specifications listed on page 5-1. Instrument specifications on page 5-1 are given for 1200 gr/mm grating at 435 nm, resolution measured with PMT and minimum slit-width. **Spectral dispersion (also called reciprocal linear dispersion) 80% of Mechanical. 3-1

66 Explanation of terms Spectral dispersion System Performance The spectral dispersion (also called reciprocal linear dispersion or linear dispersion) is a fundamental characteristic of the spectrograph, and directly affects spectral resolution, coverage, and wavelength range. These are typical values, for the spectral dispersion varies somewhat depending on the operating wavelength. The values given in the table above are given at 500 nm for a variety of gratings. Array resolution Spectral coverage Spectral range Estimating spectral dispersion The Full Width at Half Maximum (FWHM) wavelength-resolution of a spectral line on a focal plane with 26 µm pixels. The wavelength range covered by a 26.6 mm focal-plane array. The range of the wavelength drive. If no other information is available, the spectral dispersion of a grating with groove density XX may be estimated. Please note that this is only an estimate, and its accuracy depends on the grating angles. Here is the formula: Estimated SD = SD(1200 gr/mm grating) (1200/XX) 3-2

67 Slit Settings and bandpass System Performance The slit settings directly affect the spectral resolution and throughput of the system. Table VI and Table VII show the relation of slit-width to spectral bandpass under the specified conditions. Table 3-3: ihr320 slit-width vs. bandpass with 1200 gr/mm grating at 500 nm Slit-width 80 µm mm mm mm mm mm mm 9.24 Bandpass (nm)* Table 3-4: ihr550 slit-width vs. bandpass with 1200 gr/mm grating at 500 nm Slit-width Bandpass (nm)* 80 mm mm mm mm mm mm mm 5.36 *For spectrograph configuration, the pixel size in the array detector limits the instrument bandpass. For entrance slit-widths above 50 µm, the bandpass (BP) is defined by the following formula: BP = Spectral Dispersion Exit Slit-Width or Image of Entrance Slit-Width (whichever is greater). Here, BP is equivalent to Estimated Spectral Resolution with PMT or single-channel detector. Estimated Spectral Resolution with CCD (or BP of spectrograph) = Spectral Dispersion (pixel-width 3 pixels) or Entrance Slit-Width (whichever is greater) Slit-height also has an effect on bandpass, although this only becomes a factor when operating at a bandpass < 1 nm. When better resolution or smaller bandpass is required, 3-3

68 System Performance and signal strength is not an issue, it is desirable to set the height-limiter to the 1 mm setting. For additional information regarding the relationship between slit-width and bandpass, see section 2.12 of the online tutorial The Optics of Spectroscopy at 3-4

69 Stray-light rejection System Performance The ihr has been designed to minimize any stray light reaching the focal plane. The optical cavity includes blackened baffles and masks to trap unwanted light. In addition, the optical design of the ihr is free from re-diffracted light (re-diffracted light is a source of stray light that involves multiple reflections off the optical components themselves and is therefore very difficult to mask). In addition to these design features, here are some measures that the user can take to reduce stray light: Keep the f/# of the illumination at or above (narrower cone angle) the f/# of the ihr spectrograph (ihr320 f/# = 4.1, ihr550 f/# = 6.4). Use holographic instead of ruled gratings. Select a grating with a blaze angle optimized for your application. Use an order-sorting filter to remove higher orders of unwanted light. For example, when the grating is set to 600 nm, the second order of 300 nm light is also diffracted at the same position. To remove this unwanted light, a 550 nm long-pass filter can be used as an order-sorting filter to remove higher orders of light with wavelengths lower than 550 nm. The AFW-IHR internal filter, offered as an optional accessory for the ihr, is recommended for this purpose. See the online tutorial The Optics of Spectroscopy for additional information ( 3-5

71 4 : Troubleshooting Troubleshooting Introduction Following installation, some applications may require special attention for optimal system performance (see also Chapter 3: System Performance). The following troubleshooting tips are provided to help you maximize experimental results by resolving any potential problem. If you are not able to resolve the problem, please contact HORIBA Scientific. Problems Unit fails to turn on If the unit fails to turn on, check that: The power cord is connected to the power supply. The power cord is plugged into a live outlet (mains). The 5-pin DIN connector of the power supply is securely connected to the Power Connector interface of the ihr. Spectrometer does not respond to any commands If the spectrometer is powered on, but is not responding to any commands, check that: All external cables are connected (see the Connecting electrical interface cables section of Chapter 1). The system s software or firmware configuration matches the actual hardware configuration. See the software documentation for more information on creating, editing, or loading a hardware configuration. The USB port of your computer is working properly. Spectrometer responds only to some commands If the spectrometer is powered on, and responds only to some commands, check that: The failing command is valid. The parameters entered must be within limits for that drive or function. If you purchased software from HORIBA Scientific, see the provided software documentation to check that the device you want to control is configured properly. If you are running your own software, stop your program and load the software provided with the system to see if the device in question can be controlled. Your computer meets the requirements specified by the software you are using to operate the ihr. Wavelength drive or accessories do not move If the spectrometer is powered on, but the wavelength drive and/or accessories are not moving, check that: 4-1

72 Troubleshooting The grating is working properly: With the power off, remove the turret cover of the ihr and gently move the turret partially through its range of motion. When the system is powered, the device should return to its home position. All external cables are connected (see the Connecting electrical interface cables section of Chapter 1). You pay particular attention to interface-setup connections and parameters if you are using your own software program. Background signal is very high, and background is reduced when room lights are turned off If the background signal appears very high, and is reduced when the room lights are turned off, check that: All covers are securely in place. The area between the source or sample and the entrance slit is enclosed and lighttight. Block the entrance slit as a test. All openings and screw holes are plugged. Noisy signal If the signal appears very noisy, check that: There are no light leaks (see the section on Stray-light rejection in Chapter 5). If turning off the spectrometer reduces noise, rearrange power connections to be sure the spectrometer, source, and detector are tied to the same ground and, if possible, the same power circuits. 4-2

90 ihr Fully Automated Imaging Spectrometer rev. G (28 Feb 2012) 220F Fiber Adapters Introduction Components & Accessories The 220F fiber-optic adapter kit is designed for use with ihr, MicroHR, and FHR Series spectrometers, and contains 60 mm and 40 mm focal-length lenses. All kits include a centering mount which allows lateral and vertical adjustment, plus rotation of fiber position. When the adapter is mounted to an instrument slit, use the lenses to match the fiber-optic aperture to the instrument aperture. This lets you use the entire fiber-optic aperture and reduces stray light. These adapters were designed for use with optical fiber-optics with N.A. = 0.22 (f/2.3). Installation 1 Remove Fiber Adapter from packaging and inspect for damage. 2 Open sliding cover and remove plastic bags containing tools, screws, and fiber-insert. 3 Choose the type of termination of your fiberoptics and attach it to the centering mount: a For SMA termination, choose the SMA fiber-insert, place inside the centering mount, and use the small screwdriver to secure by tightening four set screws on the centering mount. b For FC/PC termination, 220F-AFC is required (not included in the 220F basic package). Choose the 220F-AFC, place inside the centering mount, and use the small screwdriver to secure insert by tightening four set screws on the centering mount. c For ¼ -ferrule termination, first insert the end of the fiber-optic through the back flange of the Fiber Adapter, then insert the ferrule into the fiber-insert. Using a 0.05 Allen key, secure the fiber by tightening the 4-40 set screw. Place the fiber-insert inside the centering mount, and use the small screwdriver to secure the insert by tightening four set screws on the centering mount. 4 To mount the Fiber Adapter on a monochromator, place front on entrance slit, line up the mounting holes, and secure in position using two cap-head mounting screws Use M3 with 2.5 mm Allen key for ihr and metric spectrometers; 8-32 with 5/64 Allen key for TRIAX.

Fiber-optic alignment and optimization 1 Check that all detector high-voltage is off. 2 Remove the instrument cover and illuminate the fiber with a visible light source. Set the slit-width to its working width (no less than 100 µm). 3 Turn off the room lights. 4 Adjust the lens closest to the monochromator (Lens 2 See Figure 3) so that the distance between it and the slit is equal to its focal length. This distance is 60 mm for the 220F. 5 Adjust the lens closest to the fiber-optic and the light source (Lens 1) so that the distance between the fiber-optic tip and lens is equal to Monochromator Lens 2 = 60 mm Lens 1 = 40 mm Centering Mount Figure 6-15: Interior of 220F with optics 6-13

Test the grating illumination by placing a white screen (such as a piece of paper or business card) in front of the grating. The full area of the grating should be illuminated. If the grating is not fully illuminated or if an area outside of the grating is illuminated, continue to adjust the lens. 6 Check to see that the light is centered by placing the screen between the entrance slit and the first active optic. You should observe a circular, homogeneously illuminated area. If the image appears disproportionate or is only partially displayed, then the light is not centered. Center the fiber using the lateral adjustment screws of the centering mount, and continue to observe the screen until the proper image is obtained. 7 To verify that light is horizontally centered, reduce the slit to its minimum width. If the top and bottom of the image appear symmetrical on the screen, then the light is approximately centered. If the image appears asymmetrical, then the light is not centered. Center the fiber using the vertical adjustment screws of the centering mount, and continue to observe until the proper image is obtained. 8 Replace the instrument cover. 9 Connect the fiber-optic to the experiment, and turn on the detector. 10 Optimize positions to get the best signal (any changes in position should be minimal). 11 Close the adapter housing and restore room lights. Typical distances d from the slit are: d Lens2 = 60 mm, d Lens1 =100 mm, d fiber = 140 mm. 6-14
