Ultra-High Speed Spatial Light Modulator

Ultra-High Speed Spatial Light Modulator

The MP-SLM-UH-1.4 is a 1024×1024 resolution LCoS reflective phase-type spatial light modulator, featuring 17 μm pixels, a 17.4 mm × 17.4 mm active array, and a Gen3 x8 PCIe controller. Its core advantage lies in its ultra‑high‑speed liquid crystal response, enabling up to approximately 1.4 kHz class 0–2π phase modulation. Combined with adjustable temperature control and purely analog phase control, it maintains excellent phase stability, diffraction efficiency, and phase accuracy even during high-speed switching. The product is widely suitable for research and industrial applications such as high-speed holography, wavefront shaping, beam shaping, adaptive optics, microscopy imaging, and high-power laser systems, meeting the demanding requirements for temporal response and phase control in advanced optical systems.

Product features：High fill factor; Fast response; Flexible temperature control; High-speed interface;
