Parallel processing dedicated LCD

A liquid crystal spatial light modulator (SLM) is a device that can change the control voltage at both ends of a liquid crystal by inputting grayscale information, enabling liquid crystal molecules to change the optical path difference of incident light. Ultra fast laser parallel processing dedicated liquid crystal spatial light modulator can change the laser'sAmplitude, phaseBy waiting for information, the laser beam splitting function can be flexibly implemented, and multiple beams can be controlled at the same timeFocus position, number of beams, beam spacingThus, efficient and precise ultrafast laser parallel processing can be achieved. The computational holography technology based on spatial light modulator can achieve flexible and controllable light field distribution, which can be accurately modulated into a preset multi focal pattern array, thereby achieving efficient parallel processing and greatly improving processing efficiency. Simultaneously utilizingspatial light modulatorIt can easily generate Bessel beams and achieve single exposure processing of micro ring structures.

American Meadowark OpticsThe company's1920x1152（P1920）The systemThe damage threshold of the column space light modulator can reach 200W/cm2, equipped with a water-cooled module to ensure constant temperature and depth of the liquid crystal. At the same time, this series of spatial light modulators has high resolution (1920x1152), large area array (17.7x10.6mm), high fill factor (96%), and high refresh rate（ 300Hz@1064nm ）High phase stability (<>)
