Optical Glass Polishing Abrasives: Choosing the Right Polishing Powder for Superior Optical Performance

Optical glass polishing is the final and most critical process in determining the imaging quality of optical components. Whether for camera lenses, microscope objectives, or high-precision optics used in laser systems, surface roughness, subsurface damage depth, and form accuracy largely depend on the polishing abrasive system. Unlike grinding, which relies primarily on mechanical material removal, optical glass polishing is a chemo-mechanical process in which both chemical reactions and mechanical abrasion work together. Therefore, the selection of polishing abrasives directly influences both the polishing process and the final surface quality.
