摘要： The present method for coating a Fresnel lens comprises providing an uncoated Fresnel lens blank having a structure surface and a non-structured surface, providing a transparent mold part having molding surface substantially matching the base curvature of the Fresnel lens, depositing a metered quantity of coating resin between the molding surface and the structured surface of the Fresnel lens, applying pressure between the Fresnel lens and the mold part while maintaining the distance between the molding surface and the structure surface so that the thickness of the coating is greater than 1.5 times the Fresnel structural height of the structured surface and less than 5 times of the Fresnel structure height of the structured surface and curing the resin coating in situ by directing the incident UV radiation at the Fresnel lens.

A double coating may be employed for obtaining both higher optical power and better mechanical properties.
