ABSTRACT:
An ultralight mirror which utilizes a light weight fibrous substrate (10), made of a tangle of silica and alumina fibers, which support a set of thin layers that form the mirror surface. These layers, from the bottom to the top, are a sealant layer (20) to plug substrate surface voids, a polished glassy layer (30), a reflective layer (40), and a protective overcoat (50).
