SiC

Lightweight optics made of Silicon Carbide are a perfect combination of material properties and polishing technologies. This ceramic material offers high stiffness, thermal stability and good thermal properties. SiC is a non-toxic replacement for Beryllium in high speed laser scanning systems without lowering the dynamic performance of the system.
