Santec's spatial light modulator (SLM) is based on reflective liquid crystal on silicon (LCOS) micro-display technology. The Santec SLM-300 high-power LCOS based spatial light modulator holds the world record for high-power durability up to CW 200 Watts. The SLM-300 has 100 times higher power durability when compared with Santec's conventional SLM product, the SLM-200.
