Investigation Of Cerium Oxide Pellets For Optical Glass Polishing

Optical glass polishing using cerium oxide abrasive bonding with resin permitted the achievement high quality surfaces in a short time. The glass surface roughness is influenced by the surface state of the cerium oxide pellet. It was found that the pellet's surface and the glass surface are abraded during the polishing process and that there is a proportionality between the removal rates of the optical glass and of the cerium oxide pellets characterised by the relative volumetric wear.
