OPTICAL ELEMENT, IMAGING OPTICAL SYSTEM, AND CAMERA MODULE |
摘要 |
An optical element incorporated into an imaging optical system, comprising: an effective diameter area that allows effective light flux contributing to imaging to pass, a non-effective diameter area that surrounds the effective diameter area; and an outer peripheral face that surrounds the non-effective diameter area. The effective diameter area, the non-effective diameter area and the outer peripheral face are centered on an imaging optical axis. At least a thickness-direction part of the outer peripheral face or a circumferential part thereof is a non-parallel face having an inclination to an imaging optical axis. A light incident from a face of an object side, reflected on a face of an image-plane side to the outer peripheral face and reflected on the outer peripheral face is not incident to an image plane.
