Optical device and vehicle optical device

Abstract

The present disclosure provides an optical device and a vehicle optical device. An optical device includes: a substrate; a light sensor located on the substrate and including a light incident surface; a protective layer located on the light incident surface side of the light sensor; and a light guide structure located between the light sensor and the protective layer, wherein incident light enters the light sensor through the light guide structure, wherein when the absolute value of the incident angle of the incident light relative to the normal of the light incident surface is larger than a first angle, the light receiving response of the light sensor is a maximum value. the first angle is greater than
