Process for producing micro Fresnel lens |
摘要 |
A process for producing a micro Fresnel lens comprising the following steps: applying a photoresist coat to a smooth-surfaced substrate such as a glass, plastic or metal plate; exposing the resist cost to actinic radiation such as an electron beam, laser beam or UV rays; developing the exposed coat to form a resist pattern duplicating concentric rings for the desired micro Fresnel lens; forming an electrode element on the resist pattern by depositing a conductive metal such as silver or nickel by sputtering or evaporation; forming a nickel layer on the conductive metal electrode element by depositing metallic nickel or a nickel compound through electroforming wherein the pattern of the concentric rings is transferred onto the nickel layer with the conductive metal being used as an electrode; forming a nickel stamper by peeling the nickel layer from both the electrode and the substrate; and forming a micro Fresnel lens on the nickel stamper by either the photopolymerization or injection method of duplication.
