Abstract
Official abstract text for this publication.
Provided are an optical element and a method of producing an optical element in which sufficient adhesion with an upper layer can be secured without damaging spectral characteristics. The production method includes the step of forming a first structural body in which a space part and a structural part are alternately and repeatedly arranged, the step of forming an etching stopper layer on an upper part of the structural part, and the step of forming a second structural body on the etching stopper layer by etching.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing an optical element comprising a first structural body and a second structural body on a base, the method comprising the steps of: forming a first structural body in which a space part and a structural part are alternately and repeatedly arranged; forming an etching stopper layer on an upper part of the structural part; covering the structural part and the etching stopper layer with a covering material; polishing the covering…
