Eyeglass lens and mold spin coater

摘要: Hard substrates such as ophthalmic lenses or molds are coated with a UV curable monomer which is polymerized to construct scratch resistant coating on surface of the lens. The present invention directed an apparatus for and method applying lens mold. Polymerization occurs by radiation light while encased in curing chamber. spin coater has following advantages: Excess collected dish away from exposure readily disposed of. substrate revolved at high rate speed during application achieve uniform monomer. Only holder moved chamber minimizing items exposed light. electrodeless, it standby mode operates cyclically use so prolong its life allow greater degree control over extent polymerization. Operation automatically can be performed using pneumatic well electronic circuits.
