Glass polishing refers to the use of chemical or physical methods to remove the surface of the glass lines, scratches and some other imperfections, to improve the transparency and refractive index of the glass, so that the glass is more glassy.
Why should optical glass be polished?
Optical glass is a kind of glass with high requirements. Optical glass should have high transparency, high uniformity in chemistry and physics (structure and properties), and specific and precise optical constants.
Therefore, the refinement of optical glass is much higher than that of ordinary glass, and polishing is a necessary process.
