3 Section 1: Introduction The Motorized Beam Expander offers an expansion range from 2.0x to 8.0x at 10.6um. This Motorized Beam Expander preserved all optical properties as manual zoom expander while offering fully motorized adjustment. This Motorized Beam Expander is designed for an alignment of zoom and divergence to facilitate adjustments on the Beam Expander. This means that manual adjustment will be avoided and it can be remotely done. With the Motorized Beam Expander, the alignment of the laser beam expansion and the divergence position of your optical system can be remotely adjusted. This can be done by two separate lens groups which are moved by two step-motors. The control box will control this two motor under the command from the computer. Assume this two step-motor is motor1 and motor2. When the motor1 running that will adjust the angle of the output beam, if motor2 running that will change the beam expander ratio. The screw lead distance is 5mm which means when the screw or motor runs for one cycle the lens mount will move 5mm. Independent movements of the lens groups are also made possible to create any desired variation of your laser beam size.

4 Section 2: Specifications Wavelength 10.6um Expansion Range x Continuous Input CA 12.0mm Output CA 39.0mm Transmission Mechanical Length 245.0mm Outer Diameter 58.0mm Pointing stability < 0.5 mrad Weight 800.0g Section 3: Control Module The beam expander control module forms the interface between computer and beam expander. The connection between controller and computer is made via a SR232 driver. While connection between controller and beam expander is made via a standard 15-pins parallel cable. The operating voltage of the controller is DC 9V. the motor used in BXZ MOT is DC motor with encoder device. The cycles the motor will run is defined by the encoder pulse. For one cycle there will be 464 DEC(01D0 HEX) pulses. If motor run one cycle, the screw will also run one cycle and the mount will run 5mm. so if the mount will run 2.5mm, then the pulses number will be 232 dec, that is 00E8 HEX. The encoder pulse is also a parameter detected by motor s encoder device, which is a pulse signal. The two motors are controlled by a control card in the control box shown as following drawing.

6 Section 4: Hardware Installation 1. Do not make any installation while laser is in operation. 2. The installation of USB to the RS232 driver 3. Connect the Control Module to Beam Expander by using the provided 15-pins parallel cable. 4. Connect the Control Module to a power supply of 9V input voltage. DO NOT switch it on at this moment. 5. Plug in the USB serial cable to the control module. DO NOT plug in the USB cable to PC until finish software installation. 6. Ensure all the connections are properly connected before switching on the Control Module. 7. For hardware, the PC USB port and control box is connected by a USB cable line. And the PC will allocate a COM number once the USB cable line is plugged into PC USB port. The COM device name is usually Prolific USB-to-Serial Comm Port ( COM X), X is the com port number. For the communication port setting: Baud rate: 9600 Data bit: 8 Parity check None Stop 1 Follow Control: None The software installed in the PC will send the command to control box to drive the motors run for specified cycles in specified direction. The detail will be introduced in segment Control Command- Transmission protocol between software and control box. COPYRIGHT 2013 WAVELENGTH OPTO-ELECTRONIC (S)PTE., LTD PUBLISHED 05/02/2013 Page 5

Send interval: Transmission time interval, generally do not change. Wavelength: According to the beam expanding wavelength to choose. 2) After the completion of installation, the motor need to be d. Note that, whenever power up the beam expander, the motor must go through initialization. 3) Choose magnification and click the GO button. 4) Trimming and memory function: When you need a specific magnification by fine-adjusting the lens gaps, please save the data first so that you may read out the data in future. The command send out by the controller will instruct the lens element move to designated location. Save 1X: Indicate to save lens data after fine-tuning the beam magnification. GO 1X: Instruct the controller command the beam expander to gain the needed magnification according to the last-saved lens data. Note: user must saves the lens data before click GO button.
