Abstract
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 surface of the mirror and polish that coating to obtain the desired figure for the complete mirror. We have developed this technique to allow the use of CFRP optics which are both stable and have a low areal density. This represents a novel use of thin film vacuum coating to produce an optical substrate rather than a simple reflective or protective overcoating and represents an advance in producing thick SiO coatings (10 - 40 micrometers) over large areas (25 - 60 cm).
