Paper Abstract

While post-polish has previously been shown to greatly enhance the surface quality, surface roughness, and surface figure of single-point diamond turned Aluminum mirrors, the field of bare Aluminum polishing continues to advance. New results demonstrating improvement in mid-spatial frequency errors and methods for adapting to a wider range of Aluminum materials constitute the next generation of polished Aluminum mirrors. These results show new levels of surface finish, correlated with BRDF measurements. Complimentary enhancements have been made by achieving new levels of precision in the placement of the optical axis relative to datum features, enabling significant alignment time savings.
