Method for producing a mold

Abstract

Disclosed is a method for producing a mold obtained by providing a monolithic optical lens element having at least a finished optical surface, the monolithic optical lens element being made of an organic material. The method includes: coating the finished optical surface with an electrically conductive material; depositing on the coated finished optical surface a layer of metal to produce a metal element having a surface which is a replication of the finished optical surface; and separating the monolithic optical lens element and the metal element, the metal element forming a mold replicating the finished optical surface of the monolithic optical lens element.
