Digital Silicon/Analog Silicon Liquid Crystal Spatial Light Modulators
SBN Series Liquid Crystal Spatial Light Modulators(SLM)
Our spatial light modulator (SLM) is based on reflective liquid crystal on silicon (LCOS) micro-display technology. The SLMs enable optical phase modulation freely and generate arbitrary 2D phase patterns on a LCOS pixel-by-pixel basis. SBN-RD series are our latest Full-HD LCOS model. The SLMs are suitable for various scientific and industrial applications, including beam shaping, wavefront correction and optical manipulations.
