Silicon Carbide (SiC) Mirrors - Zygo Corporation
Silicon carbide (SiC) has long been recognized as an attractive mirror material due to its superior mechanical and thermal properties when compared to conventional optical materials. However, the material properties of silicon carbide , which make the material attractive from a design standpoint, have often precluded its use when low cost and rapid delivery of an optical mirror were required.
