Paper Abstract

In recent years, the continuously dressed flat annular machines widely used for flat grinding have been adapted to polishing ultra-flat optical surfaces for interferometry and laser applications. This paper describes these machines and the theory and practice of their operation to achieve peak to valley flatness better than 1/10 wavelength in the visible.
