Page 20: Setup
9. Setup 9.1 setup example of the optical system Fig. 15 and Fig. 16 show examples of optical system setup using LCOS-SLM. Example 1 is an optical system using a half mirror. Example 2 shows a grazing incidence optical system. Example 2 has the advantage of less light loss due to the half mirror than Example 1.
Page 21: Installing The Rod Stand
9.2 Installing the Rod Stand As shown in Fig. 17, the LCOS-SLM head consists of a head (main body) and an L-shaped adapter. The bottom of the L-shaped adapter has a special hole (M6) for mounting the rod stand. Fig.17 LCOS-SLM Head The L-shaped adapter has a special hole for mounting various optical adjustment stages.
Page 22: Polarization Direction Of The Incident Light
Fig.18 L-Adapter Mounting Hole Drawing 9.3 Polarization direction of the incident light The LCOS-SLM has a liquid crystal orientation as shown in Fig.19. By making the polarization of the incident light the same as the orientation direction of the liquid crystal, only the phase of the incident light can be modulated.
Page 23: How To Set Dvi Video Output (Pc)
9.4 How to set DVI video output (PC) The desired signal for controlling the LCOS-SLM is generated by a PC (Windows ®). The signal generated by the PC is sent to the LCOS-SLM via the DVI port in the same way as the monitor display. A PC with a DVI port is required to drive the LCOS-SLM.
Page 24: How To
How to This section describes how to use LCOS-SLM. 1. Status after power up and warm-up time When the power is turned on, LCOS-SLM will boot for approximately 20 seconds. After a few seconds, the boot process ends and the LCOS-SLM starts operating normally. If the fan does not rotate, page.26 Please refer to "troubleshooting".

Display the attached file sample _ hologram _ hpk _ xxx _ yyynm.bmp (xxx is the LCOS-SLM head S/N, and yyy is the wavelength.) on the 2nd screen.
Page 27: Trouble Shooting
Trouble shooting  LCOS-SLM does not work or does not work properly ・ Make sure the cables are connected properly. If the cables are not connected correctly, power down the LCOS-SLM controller and reconnect them. ・ Check your PC's screen settings. The output connected to the controller is active or P.21Check if "How to set up your PC"...
Page 28 4.It may not work depending on the type of laptop. In this case, there is a way to check the operation on a desktop PC. 5.Review the Windows display settings. Due to the Windows display settings, LCOS-SLM may not receive DVI input correctly. Set the display scale to 100% from "Scale and layout"...
Page 29: Technical Explanation
Technical explanation Distortion correction pattern Since the silicon substrate of LCOS-SLM is extremely thin compared to the glass substrate, it is difficult to maintain it in a perfect plane, and initial shape distortion of several [µm] remains. Therefore, when a plane wave is made incident to emit the plane wave, the remaining distortion of the silicon substrate, which is the mirror surface, causes wavefront distortion as shown in Fig.

When inserting or removing the circulating water hose, be sure to turn off the power to the device and peripheral devices.
Page 35 ■Starting and circulating water ・Check that the circulating water is flowing normally. ・Ensure that the circulating water flow rate is 0.5 L/min. If the flow rate and water pressure cannot be ensured, replace the water circulating hose immediately. ・Do not stop the circulating water during laser irradiation. Do not stop water circulation during high-power laser irradiation.
Page 36 ■Removing the water circulation hose  Turn off the LCOS-SLM and peripherals (Include a circulating water controller).  Check that the circulating water has stopped.  Remove the circulating water hose on the circulating water controller side.  Air out the water in the circulating water hose and heat sink. ・Blow air into one side of the hose.
