A spatial light modulator (SLM) is an electrically programmable device that modulates light according to a fixed spatial (pixel) pattern. SLMs have an expanding role in several optical areas where light control on a pixel-by-pixel basis is critical for optimum system performance.

The high speed “large” format 512×512 SLM offers dynamic control of incident light with a large 12.8×12.8mm active area. This device employs a high voltage backplane in combination with a high-speed liquid crystal to push optical switching speeds even further than the standard P512 Large. As with the standard P512 Large, this device is ideal for high power applications but offers a significant boost in optical switching speed.
