Abstract
A preferred embodiment of a composite mirror comprises (1) a substrate of carbon-carbon, (2) intermediate layers of silicon carbide, silicon dioxide, (3) optically polished layers of metals and/or suitable glass (ultralow-expansion or modified fused-silica glass) and (4) an optical coating of high reflectivity. The resulting mirror exhibits desired features including high optical quality and a low coefficient of thermal expansion; such mirrors being well suited to high thermal flux applications. Methods of producing the composite mirror are described.
