This work has the potential to make a broad impact in the way that mirror assemblies are fabricated for spacecraft, satellites, and terrestrial optics. Since most NASA spacecraft and satellites require optics, the current invention may provide a path for creating high-performance mirrors while greatly reducing their cost. Moreover, the invention may result in an assembly-line-type process for fabricating mirror assemblies that will reduce the cost of terrestrial optics, such as mirrors and telescopes.
The last technique demonstrated is a localized surface treatment as a way to take a near-net shape and turn it into a mirror finish. In this technique, the BMG mirror assembly is fabricated through one of the strategies described above, but the mirror finish is left in a rough state. The mirror assembly is then subjected to a surface treatment that produces an optical mirror surface without machining, grinding, or polishing.
