Title:
OPTICAL ELEMENT MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/166851
Kind Code:
A1
Abstract:
Disclosed is an optical element manufacturing method for manufacturing an optical element that has: a supporting substrate (2); a cladding layer (3) that is provided on the supporting substrate (2); an optical material layer (4) that is provided on the cladding layer (3); and a fine pattern formed on the optical material layer. Warpage of the optical element is not less than +70 μm but not more than +2.0 mm. At least a resin layer is provided on the optical material layer, a design pattern corresponding to the fine pattern is transferred to a resin layer (5A) by means of an imprinting method using a mold (6), which has the design pattern formed therein, and the fine pattern is formed on the optical material layer by means of a dry etching method. The mold is deformed conforming to a curve of the resin layer.
