The selection of the base grinding parameters of optical glass for precision molding

Abstract

With high-performance digital cameras and measuring instruments, the demand for high-precision optical glass lenses is increasing. Molded lenses are the mainstream of optical glass lens today. The perform glass before molding requires precise machining for improvement in the form accuracy and the surface roughness. In this research, we investigated the base grinding parameters of optical glasses for precision molding with a view to reduction of polishing time of perform glasses.
