Outstanding Performance

High-Speed LCOS Spatial Light Modulator



SLM-210 is our high speed model with significantly improved response speed as a high performance product which uses its second generation LCOS technology. SLM-210 is a LCOS-SLM with a response time of less than 10 ms, which is more than 20 times faster than the conventional LCOS-SLM and it is expected to contribute to the improvement of performance in optical applications such as wavefront correction, optical beam shaping for laser processing, biosensing and quantum computing.
