LCOS-SLM (Optical Phase Modulator)
The X13138 series devices are a reflective type of pure phase Spatial Light Modulators (SLMs), based on Liquid Crystal on Silicon (LCOS) technology in which liquid crystal (LC) is controlled by a direct and accurate voltage, and can modulate a wavefront of light beam. The LCOS-SLMs are carefully designed to achieve high light utilization efficiency from various points of view, such as reflectivity, aperture ratio and diffraction noise due to the pixel structure.The X13138 series can be controlled via a PC using the Digital Video Interface (DVI), which is a standard interface for computer displays.
