Light modulator X15213-19 series

phaseliquid crystal

The X15213 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 X15213 series can be controlled via a PC using the Digital Video Interface (DVI), which is a standard interface for PC displays. The distortions in the LCOS chip, such as wavefront distortion and non-linear response of the LC, are efficiently compensated by the controller. Easy PC control, precise and linear phase modulation characteristics can be accomplished with the X15213 series. They can also provide high diffraction efficiency and high light utilization efficiency.
