Take Control of Light
Reflective Spatial Light Modulator (standard model)
SLM-200
Our reflective LCOS (liquid crystal on silicon) is an advanced spatial light modulator for full high resolution applications. WUXGA (1920 x 1200) resolution, 10-bit (1024 gray levels) and excellent phase stability (~0.001π rad.) make ultra-fine light modulation possible for various applications.
Features
■User-friendly DVI interface
■High Resolution: 10-bit (1024 gray levels)
■Ultra-low Phase Noise: ～0.002π rad.
■Super Flatness Available: λ/4 @633 nm
The flatness of the LCOS can be corrected to λ/4 with the accompanying lookup table.
Wavefront data attachment will be coming soon.
■Pattern Generator
Pattern generator is available for SLM series of SLM-200, SLM-250 and SLM-300.
The software is downloaded from the download sheet.
■SDK (Software Development Kit)
The SDK is available for SLM series of SLM-200, SLM-250 and SLM-300.
The software is downloaded from the download sheet.

Applications
■LASER Processing and High Power Resistance
Below are examples for the high power resistance. We can do simulation with other conditions.
■Wavefront Correction
Flatness up to "lambda/40” can be achieved using a Michelson Interferometer with Shack-Hartmann sensor.
■Hologram
SLM-200 can be used for holography, made easier with our exclusive GUI.
■Optical Vortex
SLM-200 can be used to generate optical vortex and be utilized for optical tweezer and SDM (Space Division Multiplexing) applications.
Beam steering
Wavefront correction
Pulse/Beam shaping
Diffractive optics
Optical tweezer
・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.
