High-Speed Spatial Light Modulator
The MP-SLM-1 is a high‑speed two‑dimensional spatial light modulator (SLM) based on Liquid Crystal on Silicon (LCoS) technology, designed for research and industrial applications requiring fast phase modulation, high stability, and high diffraction efficiency. The device employs pure analog phase control technology, supporting 0–2π continuous phase modulation, 8‑bit phase control, and a maximum modulation speed of 1 kHz, combining rapid response with excellent phase stability. The 1024 × 1024 pixel array and high fill factor enable high‑quality wavefront control and generation of complex optical fields, making it an ideal choice for adaptive optics, digital holography, beam shaping, and quantum optics.
