Abstract

SiC ceramics offer unique thermomechanical and optical characteristics. However, their practical application in optics is very limited. A novel approach was developed which combines carbon composites, carbon foam, Chemical Vapor Reaction (CVR)-Si and Chemical Vapor Deposition (CVD)-Si. This unique approach provided for a breakthrough in optical structures the elimination of the print-through at the rib section.
