LCOS-SLM (Liquid Crystal on Silicon - Spatial Light Modulator) X15213 series Control your light ! Shape your beam ! Improve your image ! 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. We also provide water cooled types with a built-in water-cooled heatsink for improved power handling capability.

LCOS-SLM (Liquid Crystal on Silicon - Spatial Light Modulator) Input readout light The LCOS chip has a parallel-aligned nematic liquid crystal layer to modulate light. It only changes the phase of light without any change of intensity and rotation of polarization state. Phase modulation is changed according to the alignment of the LC. The LC alignment is controlled, pixel by pixel, using a CMOS backplane and a DVI signal via a PC. LCOS chip DVI signal LCOS-SLM CONTROLLER Controller Reflected light Modulated only phase !

LCOS-SLM (Liquid Crystal on Silicon - Spatial Light Modulator) Operating characteristics Figure 2 Phase modulation characteristics Light utilization efficiency The X15213 series have high light utilization efficiency, which is defined a ratio of the 0th order diffraction light level to the input light level. The high light utilization efficiency mainly depends on reflectivity, and the amount of diffraction loss caused by the pixel structure. We adopted advanced CMOS technology to make the diffraction loss smaller. As a result, the diffraction loss is less than 5%. The -02/03/-04/-05/-06/-09 types...
