Take Control of Light
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) 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.
