METHOD FOR MANUFACTURING OPTICAL BEAM-SHAPING COMPONENTS

摘要

A method for manufacturing an optical component includes mounting each, of a series of replicating inserts to a movable support such as a mold slide. Each of the replicating inserts defines a replicating surface that bears micro-optical structures. Each of the supports is moved relative to one another so that the replicating surfaces of the inserts form at bast portions of surfaces of a concave geometric shape. An optically transmissive substrate is then disposed between the replicating surfaces, so that the micro-optical structures of the replicating surfaces are impressed upon externally facing surfaces of the optically transmissive substrate. Each of the mold slides are then moved away from the externally facing surfaces of the optically transmissive substrate, in a direction that is selected to preserve the impressed micro-optical structures.
