1. Introduction
1.1 Description
The santec spatial light modulator (SLM) is based on reflective liquid crystal on silicon
(LCOS) microdisplay technology. The SLM has an active matrix display with 1920 x 1200
resolution (WUXGA) and a 0.63 diagonal which enables the SLM to modulate optical
phases freely and generate arbitral 2D phase patterns (gratings, phase mask, holograms,
etc.) on a LCOS pixel-by-pixel basis. The phase response of SLM is adjusted even for
different wavelengths (450 to 1600 nm) automatically using proprietary GUI software with
built-in adjustable gamma control. The signal is addressed via a standard DVI (Digital
Visual Interface) signal e.g. by a PC’s graphics.
The SLMs are characterized by ultra-low phase fluctuation from high drive frequency over
1kHz and 10bit high resolution addressing. These abilities are suitable for various
applications including laser material processing, optical switching devices, wavefront
correction and pulse shaping.
1.2 Features
⚫Stable operation with no mechanical motion
⚫All-in-one compact design
⚫Pure, linear and precise phase control: Addressing bit depth 10 Bit
⚫Telecom qualified high reliability: Telcordia GR-1221 Core
⚫Ultra-low phase fluctuation: Typ. < 0.001 rad.
⚫Wide wavelength range (450 to 1600 nm) by adjustable gamma control

1.3 Care
The unit should not be operated in any of the following circumstances:
⚫If water or other liquid is spilled on the unit.
⚫When the unit is exposed to moisture.
⚫When the unit is cleaned or moved.
⚫If damage is found to the main cord.
⚫When the unit condenses.
Pay attention to the following guidelines for safe, trouble-free operation:
⚫Do not place in direct sunlight.
⚫Do not place in an environment with high temperature and high humidity.
⚫Do not place in an environment with dust, dirt, salt, or corrosive gas.
⚫Do not place in an area subject to large vibrations.
⚫Do not place in an area subject to noise by electric field, magnetic field, etc.
⚫Do not place in an area where the unit is subject to falling objects.
⚫Do not place in an area with possible exposure to water.
General usage guidelines:
⚫All electrical interfaces have to be connected without applied voltage.
⚫It is required to boot up the instrument AFTER connecting all devices, even if the DVI
output instrument is available.
⚫Do not touch the surface of the display because the LCD has the potential of damage
by static electricity.
⚫If you plan to illuminate the SLM with high power light or shorter wavelength light like
ultraviolet, please consult the santec service site.
⚫If you handle the LCOS unit, please wear a wristband for ESD on an earth grounded
table as shown in figure 2.
