OPTICAL DEVICE WITH RESIN THIN FILM HAVING MICRO UNEVEN PATTERN, AND METHOD AND DEVICE FOR MANUFACTURING REFLECTING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical device having a micro uneven pattern which can be formed in various three-dimensional shapes with good processing precision and made into a thin film. SOLUTION: In a method for manufacturing a resin thin film which form the micro uneven pattern by pressing a resin film 4 on the surface of a substrate 5 against a pattern material 33 having the micro uneven pattern, the substrate 5 is coated with a thin film of photosensitive resin and while the temperature of the resin thin film 4 is controlled below photosensitivity disappearance temperature and the resin thin film is softened or fused, a pressing means 2 presses the micro uneven pattern surface of the pattern material 33 against the surface of the resin thin film to form the micro uneven pattern on the surface of the resin thin film.
