Title:
OPTICAL MEMBER AND OPTICAL SYSTEM UNIT USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/009151
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical member that achieves both a high transmittance and extinction ratio for a P wave and a high reflectance for an S wave, and an optical system unit using the optical member. An optical member 10 has a wire grid part 2 where projections 2a formed by stacking a plurality of layers of different materials are arranged like a line-and-space pattern on a base material 1. The projections 2a are composed of a reflective layer 21 comprising a material of higher reflectivity than at least a layer adjacent thereto and another layer 22, with the reflective layer 21 formed at either the top or the base of the projections 2a. The thickness of the reflective layer 21 is less than the total thickness of the other layer 22.
