Abstract
Low density mirrors for optical assemblies and methods of manufacture thereof. In one example, a reflective mirror is formed of a magnesium or magnesium alloy substrate that is single point diamond turned to provide a reflective surface. The magnesium or magnesium alloy substrate is compatible with thin-film finishing processes and/or magnetorheological finishing which may be applied to improve a surface finish of the mirror.
