RESIN LAMINATED OPTICAL BODY AND METHOD FOR MANUFACTURING THE SAME
Publication/Patent Number: US2021094220A1 Publication Date: 2021-04-01 Application Number: 17/041,184 Filing Date: 2019-02-27 Inventor: Tazawa, Hiroshi   Assignee: DEXERIALS CORPORATION   IPC: B29C59/02 Abstract: There is provided a novel and improved resin laminated optical body and a method for manufacturing the same that can easily adjust an optical property other than an optical property derived from a micro concave-convex structure, and eventually can reduce manufacturing costs of an optical device. The resin laminated optical body includes: an optical base material having a curved surface; and a resin layer provided on the curved surface of the optical base material. A micro concave-convex structure is formed in a surface of the resin layer, and the resin laminated optical body has a first optical property derived from the micro concave-convex structure and a second optical property derived from a property of the resin layer other than the micro concave-convex structure, the second optical property being different from an optical property of the optical base material.
