Abstract

The embodiment of the invention discloses an optical system, a camera module, electronic equipment and a carrier. The optical system sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens from an object side to an image side along an optical axis. The optical system satisfies the following conditional expressions: 1.5 < Y1 / EPD < 3.4, wherein Y1 is the maximum optical effective diameter of the object side surface of the first lens, and EPD is the entrance pupil diameter of the optical system. According to the embodiment of the invention, through reasonable combination design of the refractive power and the surface type of the seven lenses, the optical system can meet the characteristic of a large aperture, sufficient light flux can be obtained, clearer and three-dimensional pictures can be shot at night and other environments with insufficient light, and the resolution of the optical system is improved.

Description

technical field [0001] The present application relates to the technical field of optical systems, in particular to an optical system, a camera module and electronic equipment. Background technique [0002] In recent years, with the continuous development of science and technology, portable electronic devices such as smart phones and tablet computers have become an indispensable part of people's lives, and the camera modules mounted on electronic devices are also becoming more and more diverse.
