Take Control of Light
Spatial Light Modulator
Our LCOS-SLM (liquid crystal on silicon based spatial light modulator) is an advanced spatial light modulator for full high resolution applications. The Full-high definition (Full-HD) resolution, 10-bit (1024 gray levels) and excellent phase stability (~0.003π rad.) make ultra-fine light modulation possible for various applications.
What is a spatial light modulator?
Spatial light modulator is a 2 dimensional phase modulation devise. SLM enable to control 2 dimensional light signal to achieve hologram image, beam deflection and arbitrary beamshape by use of a SLM. SLM has been deployed in a various applications, such as 3D printer in UV, cell manipulation in VIS and laser processing in IR.

UV Hardened Spatial Light Modulator
SLM-250
Reflective LCOS (Phase only)
We have introduced an ultraviolet (UV) hardened spatial light modulator (SLM) based on Liquid Crystal on Silicon (LCOS) technology. This product supports WUXGA (1920×1200) and Full-HD (1920×1080) video resolutions. The 2nd generation SLMs from Santec offer 4 times better gray scale resolution and 10 times better phase stability when compared with conventional products in the market and the 1st gen Santec SLMs.
The UV model SLM (SLM-250) has a 42 times higher UV tolerance compared to the visible to Infra-Red (IR) wavelength SLM-200. A power density up to 10mW/cm² is sustainable using a novel liquid crystal and dielectric mirror design.
The SLM-250 follows the popular first generation SLM-100 from Santec that has been deployed in various industrial and scientific applications, including beam shaping, computer-generated holograms, optical manipulation, and wave-front compensation.

・Laser Processing Machine (※)
We are developing a Laser Processing Machine incorporating a SLM with Professor Yamamoto and Associate Professor Taira, faculty members at the Institute for Molecular Science.
Associate Professor Taira has developed the high power compact microchip laser, which is suitable for laser processing with one shot method.
The technique is constantly refined, adapting emerging technologies and techniques to provide higher efficiencies and quality.
