Problems solved by technology

However, the increase in the number of lenses increases the difficulty of processing and assembling the lenses, and increases the volume of the optical lens.
Therefore, in the related art, under the design trend of thin, light and miniaturized optical lenses, the image quality of optical lenses is poor, the resolution is low, and the imaging quality of optical lenses is not clear enough, it is difficult to meet people's high-definition requirements of optical lenses. imaging requirements

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, a sixth lens element, a seventh lens element and an eighth lens element which are sequentially arranged from an object side to an image side along an optical axis. The first lens element has positive refractive power; the second lens element has negative refractive power; the third lens element has positive refractive power; and the eighth lens element has negative refractive power. The optical lens meets the following relation: 2mm < SD82 / FNO < 3.5 mm, wherein SD82 is the maximum effective half aperture of the image side surface of the eighth lens element, and FNO is the reciprocal of the relative aperture of the optical lens. According to the optical lens, the camera module and the electronic equipment provided by the invention, a light, thin and miniaturized design can be met, meanwhile, the characteristic of large aperture is achieved, the shooting requirement of a large field angle is met, the picture texture of the optical lens is improved, the resolution ratio and the imaging definition of the optical lens are improved, and clear imaging is achieved.

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, which not only requires optical lenses to be thinner, lighter and smaller, but also to achieve higher imaging quality. In order to achieve higher imaging quality, optical lenses need to increase the number of lenses to correct aberrations. However, the increase in the number of lenses increases the difficulty of processing and assembling the lenses, and increases the volume of the optical lens. Therefore, in the related art, under the design trend of thin, light and miniaturized optical lenses, the image quality of optical lenses is poor, the resolution is low, and the imaging quality of optical lenses is not clear enough, it is difficult to mee...
