3 Section 1: Introduction Wavelength Opto-Electronic(s) Pte Ltd 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.

Insert the installation CD into your CD drive. 2. Start installation by clicking the " Setup.exe ". 3. After the installation is completed in the computer desktop will be displayed as shown in the following image Icon COPYRIGHT 2013 WAVELENGTH OPTO-ELECTRONIC (S)PTE., LTD PUBLISHED 05/02/2013 Page 5

7 4. Operation of the main interface as shown in figure: 1) Click the SETTINGS button to pop up the following interface 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 COPYRIGHT 2013 WAVELENGTH OPTO-ELECTRONIC (S)PTE., LTD PUBLISHED 05/02/2013 Page 6

8 Serial Port: The specified device serial port number, generally do not change. Port setting: Transmission protocol communication, generally do not change. 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.

9 Section 6: Communication and Protocol 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. Wavelength-tech provides Motor_control.exe, DLL and command list to support system integration. COPYRIGHT 2013 WAVELENGTH OPTO-ELECTRONIC (S)PTE., LTD PUBLISHED 05/02/2013 Page 8

10 The Motor_control.exe is the software with GUI developed by Wavelength-tech which could run independently to control the motor for zoom beam expand ratio. This software has a friendly interface for operating, shown as follows. For the detail of Motor Control.exe please have a view on software manual.

11 Motor Control.exe employs a DLL developed by wavelength-tech to send the command to control box. The configuration or structure of this software is shown as following drawing. The host computer sends command of 7 bytes data to the control box, the control box to control two motor by receiving data command. For the detail description about the command please Read Section 7 command list Section 7: Command list 7.1 Control Command- The Transmission Protocol between Software and Control Box. In the motorized beam expander, there are two DC motor. The control box will drive this two motor under the command from the pc. The command will indicate which motor will run first and the cycles the motor will run. this two motors is named motor1 and motor2. If motor1 runs, the middle lens group will run, which will adjust the angle of output beam. If motor2 runs, the input side lens group will run, which will change the beam expand ratio. The control command sent from pc to control box should be 7 Bytes code. Each byte is shown as a hex as follows: Byte1 st byte2 nd byte3 rd byte 4 th byte 5 th byte 6 th byte 7 th For an example, software sends a command to control box. Here 01(HEX) is Byte1 st and 00 (HEX) is byte2 nd then 04(HEX) is byte 7 th. The description of Byte1 st to byte 7 th is shown as follows: Byte 1st Byte 2nd Byte 3rd Byte 4th Byte 5th Byte 6th Byte 7th Byte Function Indicates which motor 01/02 run first Indicates the direction of movement of motor 01 Represents the high byte (hex) of pulse number of the motor 01 Represent s the low byte (hex) pulse number of the motor 01 Indicates the direction of movement of the motor 02 Represe nts the low byte (hex) pulse number of the motor 02 Represe nts the low byte (hex) pulse number of the motor 02 COPYRIGHT 2013 WAVELENGTH OPTO-ELECTRONIC (S)PTE., LTD PUBLISHED 05/02/2013 Page 10
