Recent progress on magnetic aided optical polishing of CIOMP

Abstract

Sub-aperture polishing technologies, including CCOS (Computer controlled Optical Surfacing), CCP (Computer controlled Polishing), MRF (Magnetorheological Finishing), IBF (Ion Beam Figuring) etc., are widely used for aspheric optical surface polishing. Because magnetic aided optical polishing could reach both high accuracy and low sub-surface damage, CIOMP cooperated with Belarusian National Technical University (BNTU) and A.V. Luikov Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus (HMTI) respectively to develop magnetic aided polishing technologies for aspheric optics since 2008.
