Liquid crystals
light valve

HOASYS Liquid Crystals Light Valves (LCLV) are optically addressable spatial light modulators. No preimposed pixelized structure permits to avoid diffraction losses and transparent electrodes are optimized to avoid  thermal effects.

HOASYS LCLVs are custom based solutions in order to address customer needs.
