Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens includes first lenses with negative refractive power arranged sequentially along the optical axis from the object side to the image side, and the side of the object is concave; The second lens, its image side is concave; the third lens with refractive power, its object side is convex; the fourth lens, the fifth lens, and the sixth lens with refractive power; the seventh lens with refractive power, its object side The side is convex; among the first lens to the seventh lens, at least one surface is non-rotationally symmetrical; at the same time, the optical lens satisfies 36°<(FOV / TTL)*f<45.5°, and FOV is the maximum field of view angle of the optical lens , TTL is the distance on the optical axis from the object side of the first lens to the imaging plane of the optical lens, and f is the effective focal length of the optical lens. The optical lens, camera module and electronic equipment provided by the present invention can realize miniaturization, thinning, large viewing angle and high-quality imaging.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] At present, with the development of camera technology, various electronic devices equipped with camera modules (such as digital cameras, smart phones, notebook computers, tablet computers, etc.) are widely used. Due to the increasing requirements on the portability of electronic devices, the size requirements for camera modules mounted on electronic devices are correspondingly more stringent, that is, the miniaturization and thinning of camera modules has become an inevitable development requirement. However, while realizing miniaturization and thinning of the camera module, the field of view and imaging quality of the camera module will be greatly affected, which cannot meet the design requirements. Therefore, how to achieve a large field of view and improve the imaging effect while...
