Buying Spatial Light Modulators
Spatial light modulators (SLMs) are devices that introduce spatially dependent intensity or phase changes in a controlled manner. Based on technologies like liquid crystal and MEMS, they are used in applications such as image projection, holographic data storage, optical computing, and ultrashort pulse shaping.
