Advantages of Square & Rectanglular Sapphire Windows

CRYSCORE carries a variety of rectangular sapphire window dimensions. The sapphire windows are polished by special CMP (Chemical Mechanical Polishing) technology at CRYSCORE, to get high surface quality at low cost. For the extensively used C-plane (0001) sapphire windows, the surface roughness is lower than 0.2 nm.


We are down-to-earth, working forward our goal of becoming one of the best sapphire window manufacturers in the world.
