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

■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.

1) Specification on the defect pixels are no object.
2) Zero-order reflection.
Depending on specified wavelength range.
3) Response time is a typical value and is not affected by frame rate.
Tr: Rise time between 10% and 90% levels in a phase change of 0 to 1023 bit (2π rad.) at 25℃.
Tf: Fall time between 90% and 10% levels in a phase change of 1023 to 0 bit (2π rad.) at 25℃.
4) The value is not guaranteed.Depending on the conditions of the laser oscillator used,
the product's life may be significantly shortened due to accumulated exposure time.

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.
