First Claim
Patent Images
1. A method for manufacturing an optical element, comprising:
- forming plural linear resist films arranged at equal intervals on a transparent electrode layer formed on a glass substrate;
performing a process of forming a first metal layer made of a first metal by an electrolytic plating process and then forming a second metal layer made of a second metal by an electrolytic plating process or non-electrolytic plating process, thereby forming the first metal and second metal alternately on each other between the resist films; and
removing the resist films to leave a wire grid in which the first metal and second metal are alternately formed,wherein the first metal is a different metal than the second metal, andwherein the process of forming the first metal layer and then forming the second metal layer is performed at least twice until a configuration having a desired number of the first and second metal layers is obtained.
