UV hardened Spatial Light Modulator SLM-250(:502KB)
Reflective LCOS (Phase only)
SANTEC has introduced an ultraviolet (UV) hardened spatial light modulator (SLM) based on Liquid Crystal on Silicon (LCOS) technology. This product support WUXGA (1920×1200) and Full-HD (1920×1080) video resolutions. The 2nd generationSLMs from Santec offer 4 times better 10-bit (1024 gray level) 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.
