Abstract

The invention discloses an optical lens, a camera module and electronic equipment. The optical lens comprises a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element which are sequentially arranged from an object side to an image side along an optical axis. The first lens element with positive refractive power has a convex object-side surface and a concave image-side surface, respectively. The second lens element with negative refractive power has a convex object-side surface and a concave image-side surface, respectively. The sixth lens element with negative refractive power has a concave image-side surface. The optical lens satisfies the following relation: 1.3 mm < Imh^2 / TTL / Fno < 1.42 mm, wherein TTL is the distance from the object-side surface of the first lens to the imaging surface of the optical lens on the optical axis, Imgh is half of the length of a diagonal line of an effective pixel area on the imaging surface of the optical lens, and Fno is the number of apertures of the optical lens. According to the optical lens, the camera module and the electronic equipment provided by the invention, the picture quality of the optical lens can be improved while the optical lens is designed to be light, thin and miniaturized, and the resolution and the imaging definition of the optical lens are improved.

Description

Technical field [0001] The present invention relates to a technical field of optical imaging and more particularly relates to an optical lens, a camera module and an electronic apparatus. Background technique [0002] Now, with the development of camera technology, people increasingly high image quality optical lens requirements, and light structural characteristics of miniaturization is becoming the development trend of optical lens. In the related art, in the light satisfying the optical lens design trends of miniaturization, the optical lens poor quality sense, lower resolution, and image quality of the optical lens is also not clear enough, it is difficult to meet the requirements of high-definition imaging optical lens . Inventive content [0003] Example discloses an optical lens, a camera module and an electronic apparatus according to the present invention, while achieving a thin optical lens, compact design, the optical lens to improve image quality sense, increasing th...
