Abstract

A method of fabricating a deposited concave mirror substrate (40) includes adjusting the background pressure in a vacuum system (3) and interposing a mask (50) between a directed flow of deposition material (60) and a flat base (30) so that the deposition material forms a concave substrate (40) on the base (30).
