Abstract:
1. A process for producing an optical surface on a metallic monolith, which process comprises: providing a metallic monolith; forming a bevel on the metallic monolith; pre-polishing a surface of the metallic monolith to produce a pre-polished surface having a surface roughness of not more than 100 angstroms rms with a surface accuracy in terms of surface figure error of not more than about one-half of a wave peak-to-valley; polishing the pre-polished surface with a polishing agent comprising an aqueous dispersion of abrasive particles, a catalyst, and an organic solvent to produce a polished surface having a predetermined surface roughness with a surface accuracy; and cleaning the polished surface to remove the polishing agent therefrom.
