Abstract
An imaging element includes a plurality of pixels that are two-dimensionally arranged and each have a light receiving part including a photoelectric conversion element and a light collecting part that collects incident light toward the light receiving part. Each of the light collecting parts in the plurality of pixels includes an optical functional layer having, in a surface, a specific projection and depression structure depending on the pixel position.
Claims24
An imaging element, comprising:
- a plurality of pixels configured to be two-dimensionally arranged, the plurality of pixels comprising:
- a first pixel, comprising:
- a first photoelectric conversion element;
- and
- a first light collecting part configured to collect incident light, wherein the first light collecting part comprises a first projection and depression structure;
- and
- a second pixel, comprising:
- a second photoelectric conversion element;
- and
- a second light collecting part configured to collect the incident light, wherein the second light collecting part comprises a second projection and depression structure,
- wherein a first aspect ratio of the first projection and depression structure is equal to a second aspect ratio of the second projection and depression structure.
