Nikn Decnvlutin Micrscpe Quickstart Guide Fr NIS v4.30.01 Guide V1.02, updated August 19, 2016. Startup Turn n the PC. Lg nt the PC, wait until Windws has finished lading (~60 sec). The chamber is set t 37 C, measured via a thermcuple within a small dish n the micrscpe stage. The thermcuple must be immersed in water. Add water as necessary. If yu require CO 2 Incubatin, Duble Click the CO 2 On icn n the desktp. Nte that it may take ne-half hur r mre fr the CO 2 level t stabilize. Duble Click the NIS icn n the desktp t turn n the micrscpe and lad the capture sftware. This will als cnfigure yur data file paths. Basic Navigatin Nte; there are three basic prgram screens (and mdes). Tabs fr these are presented in the lwer left crner f the mnitr display. The initial prgram screen is the ND Acquire screen. This is best used fr imaging single r a few selected pints in ne r a few slides r dishes. The Multiwell screen brings up JOBS mde, which can run cmplex experiment macrs, and is best used fr repetitive, multiple pint captures with multiwell plates, etc. The third screen is Measure, which prvides access t a range f measurement and image analysis ptin during and pst acquisitin. Basic Visualizatin and Setup (Cmmn t bth ND Acquire & JOBS mdes) Select the bjective yu wish t use frm the Macr Panel: the apprpriate DIC r phase rings will mve int place alng with the bjective (1). If yu are using an il immersin bjective, carefully clean the lens with a lens tissue. Place a drp f il n the bjective. Install the apprpriate sample hlder adaptr i.e.: 3 place slide, 4 place petrie dish, etc. and munt yur sample. Set the XY stage speed t Carse n the jystick by twisting the jystick knb and centre yur sample ver the bjective. Select Eyepiece Mde (2) (n the Macr Panel). Select the Optical Cnfiguratin yu wish t use frm the OC Panel (3), and ensure it is highlighted green. Chse either: Quad Band with Bleedthrugh quad-band dichric and quad-band emissin filter. Quad Band w/ Bleedthrugh quad-band dichric and individual band-pass emissin filters. Triple w/ Bleedthrugh triple-band dichric and individual band-pass emissin filters.
Dual w/ Bleedthrugh dual-band dichric and individual band-pass emissin filters. Other single dichric and band-pass emissin filters. Clur Brightfield false clur imaging f brightfield images. Permits assembly f realistic full clur verlays. If yu wish t perfrm brightfield imaging, slide the plariser unit situated abve the micrscpe cndenser t the pen psitin. The brightfield lamp is turned n via the push buttn n the small black bx lcated t the left f the micrscpe. Adjust brightness there als, via the rtary knb. Bring the bjective up using the micrscpe carse fcus knb until the il tuches the cverslip (if yu are using immersin il). Fcus n yur sample using the eyepieces, r via the Fcus Light n the frnt f the micrscpe. Nte: the LCD panel n the micrscpe displays the Z psitin. Crrect fcus is typically between 4000 & 6500μm. Set the XY stage speed t Fine r Ex Fine n the jystick, and centre an bject f interest. Select Live Image (r Snap Image if yu want t minimise bleaching) frm the Macr Panel. Nte: Selecting the Stp buttn will terminate the live image update and sample illuminatin (4). Select the image size yu wuld like: ROI OFF (2048x2048), ROI 1024x1024 r ROI 512x512 (5). We recmmend yu adjust camera expsures manually via the drp dwn list n the Flash4.0 Settings Panel (6). Hwever, expsures can be set autmatically using the Aut-Expsure buttn. The size and psitin f the autmatic expsure calculatin area can be set by selecting the Prbe buttn n the right hand side f the image windw). Turn n the Pixel Saturatin Indicatr (7) and the aut Lk Up Table (8) in the tlbar abve yur image. If necessary, yu can adjust the LED brightness (default = 75%) by clicking n the OC Panel title bar and then selecting Spectra Pad (9). Hwever, if yu change the lamp LED brightness, yu will ntice when returning t the OC Panel that the currently selected OC bears a red exclamatin mark. This is a warning that a setting has been mdified. T prceed, save the change by clicking n the small arrw next t the red exclamatin mark. Select the Muse XY buttn (10) in the tlbar abve yur image, then click n yur image, hld dwn the left muse buttn and drag the muse t mve the mtrised XY stage. Rll the muse wheel t adjust the fcus (ttal travel = 200μm). Yu can centre an bject f interest by duble clicking the left muse buttn with the cursr n the bject f interest. Fcus n an bject f interest. Either: Adjust the fcus autmatically by pressing the AutFcus buttn (#) (yu can mdify the aut-fcus settings under the Devices > Aut Fcus Setup menu),
OR Adjust the fcus manually by scrlling the muse wheel, the micrscpe r jystick fcus knb. Once the sample is in fcus, adjust the expsure settings again either manually r using the Aut-Expse buttn, ensuring that the captured image is nt ver-expsed. NB. Saturated pixels will NOT decnvlve, s it is much better t have a weak image than a bright ne. Repeat fr all ther desired Optical Cnfiguratins (flurphres, channels, etc.). Expsure times are aut-saved when they are mdified. Nte: at this stage it is pssible t perfrm a simple ne clur capture, if desired, by clicking Snap Image (11) n the Macr Panel. The methd f setting up a mre cmplex experiment n the ND Acquire and Multiwell (JOBS) screens diverges at this pint. Perfect Fcus (PFS) The Perfect Fcus System is a hardware based autfcus, that utilises an IR LED t fcus n the sample side f the cverslip. The user may then tell the system hw far away (ffset) the sample is frm the cverslip. PFS requires a refractive index change t detect the cverslip, such as a liquid sample munting media, and may nt wrk with fixed slides. T set up: Fcus n yur sample. Press the PFS buttn n the frnt f the micrscpe. If viewing a live image, the sample may well appear t defcus. Hwever, if the small recessed green FOCUS LED next t the PFS buttn lights up, PFS is wrking. Adjust the PFS fcus cntrller r muse wheel (nt the micrscpe) t refcus yur specimen (determine the ffset). When cnfiguring a multipint ND acquisitin, it is essential that PFS is turned n befre yu recrd each pint. If nt, PFS will nt functin during the experiment. If imaging mre than ne 35mm dish in an experiment, ensure that Keep PFS On During Stage Mve in the XY Overview tab is NOT ticked, r PFS may fail when the metal stage insert mves ver the bjective. Nte: if the micrscpe triple beeps, r yu dn t see the small FOCUS LED light up, try adjusting the micrscpe fcus up and dwn until yu get PFS t wrk. Yu can make the micrscpe remember the PFS fcus psitin fr each bjective by pressing the Memry Buttn nce PFS fcus lck is achieved, hwever this will be lst when the micrscpe is pwered ff.
