Take Control of Light
UV Hardened Spatial Light Modulator
SLM-250
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) 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.
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 wavefront correction.

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.
