Glass Grinding

Glass lenses reduce anti-reflection and block optical noise through multiple processes of cutting，
grinding, polishing, centering, coating and inking.
Currently, such glass lenses are the mainstream of the market.

Glass material -> Milling -> Grinding -> Polishing -> Centering -> PVD (Coating) -> Bonding/Inking
