Weight of telescope mirror reduced by 60%

Optical Surfaces has produced lightweight mirrors that combine optical performance, structural strength and component weight reduction.

Ultra-high precision telescope mirrors that do not increase payload weights are increasingly required for telescope-based experiments conducted outside the Earth's atmosphere. Lightweight mirrors also allow the creation of larger terrestrial telescopic instruments than wouldn't be feasible with solid mirrors. Optical Surfaces claims its lightweighting techniques can reduce the weight of the mirror by as much as 60%.

These lightweight mirrors provide rigidity for ultra-high precision optical performance while reducing the weight of the mirror. The reduced weight, in turn, allows smaller, lighter support and control structures, reducing the overall cost of the telescope.

Optical Surfaces' team of technicians and engineers is able to produce highly aspheric, fast focusing (to f 0.5) parabolic mirrors with high performance aspheric lenses featuring tight tolerances, low surface scatter (20-10 scratch-dig) and high surface accuracy (lambda/20).
