The primary purpose of this proposal is to develop and demonstrate a new technology for manufacturing an ultra-low-cost precision optical telescope mirror which can be scaled up for use in very large UV/optical and/or infrared telescopes. This proposal will demonstrate prototype manufacturing of a precision mirror in the 0.25 to 0.5 meter class, with a specific scale up roadmap to 1 to 2+ meter class system which can be rated for space flight. Material behavior, processing parameters, optical performance, and mounting techniques will be demonstrated. The potential for scale-up will be addressed from a processing and infrastructure point of view. The Phase 1 deliverable will be a 0.25 meter proof-of-concept mirror. Its optical performance assessment and all data on the processing and properties of its substrate material will be determined. UMS proposes to demonstrate the feasibility of forming a polymer derived 'bulk ceramic' mirror substrate with a 'fully dense' optical surface. This mirror substrate with fully dense surface, will be optically figured, polished and coated with a reflective metal system typically used in a commercial terrestrial telescope.
