Abstract
SiC optics have been considered for numerous optical applications for a long time. The fundamental limitation of monolithic SiC is its, very low fracture toughness which greatly limits its reliability. Long fiber, SiC-SiC composites are an excellent candidate for high end optical application. The selection of the fiber and composite processing needs to address the intrinsic issues of modulus, strength, toughness, thermal conductivity and CTE isotropy. The adaptability and flexibility of SiC-SiC composite manufacturing renders the ability to fabricate very complex, closed-back structures. The fundamental issues associated with uv optics is the ability to polish the substrate to ultra high quality in order to greatly reduce the scattering.
