Optically active structure application method for Fresnel lens manufacture, involves photographic structuring photosensitive resist layer, coating substrate with optically active layer and lifting-off resist layer

摘要

The method involves coating a substrate (1) with a photosensitive resist layer and carrying-out photographic structuring of the resist layer. The pre-structured substrate is coated with an optically active layer comprising glass and metal, by electron beam physical vapor deposition (E-beam PVD) and the resist layer is lifted-off. Independent claims are also included for the following: (1) optically active element; (2) optically active component; and (3) hybrid lens.
