Paper Abstract

The newest achievement of super smooth processing technology of optical element bowl-feed polishing (BFP) is described. The need background and developing tendency of super-smooth optical elements are analyzed. The key problems of BFP have been found, the process parameters have been determined, and the basic method of BFP has been worked out by the study of process factors and processing principle. Φ50 mm k9 glass sample with 0.5 nm surface roughness and better than λ/8 surface shape has been processed.
