Paper Abstract

Diamond turning and precision generation of aspheric metal surfaces has promoted a change in lapping techniques due to the extremely close figure tolerances and surface finishes that have been achieved. In order to polish the unusual aspheric figures, we utilized special tooling, diamond abrasive, and silicon oil and techniques which we will describe in detail. Our studies include small flat diamond turned samples of copper, electroplated copper, electroplated silver, electroplated nickel and silver as well as large aspheres such as an f/0.75, 35 cm diameter copper ellipse. Results from cleaning studies on flat samples using ultrasonics and vapor degreasers will also be summarized. Interferograms of wavefront distortion and analysis of focal volume i ll ll be included as well as 10.6 pm reflectivity and a summary of laser damage experiments.
