28 August 1998 Sol-gel coating of composite mirrors to provide a surface for optical figuring

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 temporal stability, but replicated surface accuracy limited to millimeter applications. The solgel coatings of 20 to 200 micrometers thickness provide a surface which can be optically ground, polished, and figured to provide IR and optical quality mirrors. We have demonstrate this with both flat and concave spherical mirrors.
