OPTICAL LENS, CAMERA MODULE, AND ELECTRONIC APPARATUS

WIPO Patent Application WO/2022/174724

A1

An optical lens, a camera module and an electronic apparatus. By means of the optimization and fitting of parameters of each lens, imaging of the optical lens is also guaranteed to have a smaller distortion under the condition that the optical lens can have a larger field of view. Specifically, a first lens is a lens bent toward an image side, and the first lens is a lens having a negative refractive power, such that a scene in a larger field of view can fit into the optical lens, and a field of view angle of the optical lens is improved. Further, an object-side surface of a sixth lens and/or a seventh lens has at least one inflection point, such that the sixth lens and/or the seventh lens have/has a better effect of adjusting optical distortion and eliminating aberration, and the distortion of the optical lens can be further reduced, so as to guarantee that the optical lens can have a smaller distortion while having a larger field of view angle.
