Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from an object side to an image side along an optical axis; the object side surface and the image side surface of the first lens are a plane and a concave surface respectively; the image side surface of the second lens is a concave surface; the object side surface and the image side surface of the third lens are convex surfaces; the object side surface and the image side surface of the fourth lens are concave surfaces; the object side surface and the image side surface of the fifth lens are convex surfaces, and the object side surface of the sixth lens is a convex surface; the optical lens meets the following relation: 3.5 < f45/f < 10, f45 is the combined focal length of the fourth lens and the fifth lens, and f is the effective focal length of the optical lens. According to the optical lens, the camera module and the electronic equipment provided by the invention, light rays emitted into the optical lens at a large angle can be grasped while the light, thin and miniaturized design is met, the shooting requirement of a large field angle can be met, and clear imaging can be realized.

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, people have higher and higher requirements for the imaging quality of optical lenses, and at the same time, the structural characteristics of lightness, thinness and miniaturization have gradually become the development trend of optical lenses. In related technologies, under the design trend of light, thin and miniaturized optical lenses, the field of view of the optical lens is small and the resolution is low, it is difficult to meet the shooting and clear imaging of a wide range of angles, so that it cannot meet the shooting of a large field of view need. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module and an electronic device, which can not only realize the light ...
