PROCESS FOR APPLYING A COATING ONTO A FRESNEL LENS FORMING SURFACE |
摘要 |
Disclosed is a process for coating at least one geometrically defined surface of an optical article's substrate. The process can include: (a) providing a removable carrier made of plastic material and having an internal surface and external surface; (b) providing an optical article comprising a substrate having at least one geometrically defined surface forming a Fresnel lens; (c) depositing a curable coating composition onto either the at least one surface forming a Fresnel lens; (d) moving the carrier and optical article relatively to each other; (e) applying a pressure onto the external surface of the carrier to spread out the curable coating composition to cover said at least one surface forming a Fresnel lens; (f) curing the layer of curable coating composition; (g) withdrawing the removable carrier to recover the substrate of the optical article having at least one Fresnel lens forming surface coated with the cured coating composition. |
