The cost and leadtime associated with beryllium has forced the MDA and other defense agencies to look for alternative materials with similar structural and thermal properties. The use of carbon-carbon material, specifically in optical components has

Future space telescopes require primary mirrors that are much lighter than those currently being manufactured. They also must maintain optical tolerances while operating at cryogenic temperatures. We present a Mirror System Demonstrator for the Next

Recent developments in the design and fabrication of very light-weight all-composite mirrors have made possible extremely well balanced, thermally stable, structures which distort very little when cooled. One such mirror is the Composite Optics, Inco

We have achieved reliable, repeatable coatings of solgel- deposited glass on Carbon Fiber Reinforced Plastic sandwich panel mirrors of sizes 10 to 90 cm. Very lightweight CFRP panels up to 2 meter size have been produced with high thermal and tempora

We have been able to utilize silicon monoxide (SiO) as a refractory coating to improve on the replicated figure of composite optics made from carbon fiber reinforced plastic (CFRP) sandwich panels. We apply an evaporative coating of SiO to the surfac

As part of a design study for a balloon-borne 3-m telescope for far-infrared and submillimeter astronomy, it has been necessary to test and evaluate the state-of-the-art for ultra lightweight primary mirror material candidates. In addition to being u
