Title:
OPTICAL ELEMENT, IMAGING ELEMENT, AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/113352
Kind Code:
A1
Abstract:
An imaging element (100) comprises: a transparent layer (150) for covering a plurality of pixels (130) each including a photoelectric conversion element; and a plurality of structures (160) disposed on the transparent layer (150) or in the surface direction of the transparent layer (150) within the transparent layer (150). The plurality of structures (160) are disposed so as to, according to the incidence angles of incident light rays on the respective structures, concentrate light rays of a first color among incident light rays onto a first pixel located immediately thereunder and concentrate light rays of a second color onto a second pixel located immediately thereunder.
