Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises from an object side to an image side along an optical axis: a first lens, wherein the first lens has positive refractive power, and the object-side surface and the image-side surface of the first lens are convex and concave surfaces near the optical axis; a second lens with negative refractive power, wherein the second lens has an object-side surface and an image-side surface being convex and concave in a paraxial region thereof; a third lens with positive refractive power , wherein the third lens has an object-side surface being convex in a paraxial region thereof; a fourth lens which has an object-side surface being concave in a paraxial region thereof; a fifth lens with negative refractive power, wherein the fifth lens has an object-side surface and an image-side surface being concave and convex in a paraxial region thereof; a sixth lens with positive refractive power; a seventh lens, wherein the object side surface of the seventh lens is a convex surface at the optical axis; and an eighth lens with negative refractive power, wherein the eighth lens has an image-side surface being concave in a paraxial region thereof. The optical lens satisfies the following relational expression: f / EPD is more than or equal to 1.62 and less than or equal to 2.16. The optical lens, the camera module and the electronic equipment provided by the embodiment of the invention have the characteristics of large aperture and large image plane, and can realize 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] With the development of science and technology, the specifications of electronic products are changing day by day, and the optical lenses among the key components are also more diversified. They not only pursue thinness and good imaging quality, but also pursue the design of large aperture and large image area. At present, there is an increasing market demand for the thinning of the existing optical lens and the design of the required aperture value. However, how to increase the aperture value of the optical lens and shorten the length of the lens while maintaining good imaging quality is a huge challenge in the industry. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module and an electronic device, which can achieve miniaturi...
