Title:
OPTICAL BODY, WINDOW MATERIAL, FITTING, SUNLIGHT SHADING DEVICE, AND ARCHITECTURAL STRUCTURE
Document Type and Number:
Japanese Patent JP2012003024
Kind Code:
A
Abstract:

To provide an optical body capable of maintaining an excellent upward reflection performance and suppressing light absorption by a wavelength selective reflection layer.

An optical body has a first optical layer having a rugged surface, a wavelength selective reflection layer formed over the rugged surface, and a second optical layer formed over the wavelength selective reflection layer so as to bury the rugged surface. The wavelength selective reflection layer reflects directionally and selectively light of a specific wavelength band and transmits light of a wavelength band other than the specific wavelength band. The rugged surface is composed of a plurality of bodies having a shape similar to a triangular column arranged in one dimension, and the body having the shape similar to the triangular column has a vertex angle α and a slope angle β with the vertex angle α and the slope angle β satisfying a prescribed relation.
