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, a sixth lens, a seventh lens and an eighth lens 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 an object-side surface being convex in a paraxial region and an image-side surface being concave in a paraxial region. The second lens element has an object-side surface being convex in a paraxial region and an image-side surface being concave in a paraxial region. The third lens element with positive refractive power has an image-side surface being convex in a paraxial region thereof. The fourth lens element has negative refractive power. The fifth lens element has an object-side surface being concave in a paraxial region thereof. The sixth lens element has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The seventh lens element has an object-side surface being convex in a paraxial region and an image-side surface being concave in a paraxial region. The eighth lens element with negative refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof.

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] In the related art, for an optical lens with a large aperture number, its volume is often large, which cannot meet the miniaturization requirements of the optical lens; for an optical lens with a small volume, its aperture number is small, resulting in a small luminous flux and dark The image quality in the environment is poor. That is, it is difficult for the optical lens in the related art to be designed with both miniaturization and large aperture. Contents of the invention [0003] The embodiment of the present invention discloses an optical lens, a camera module and an electronic device. The optical lens can take into account the advantages of miniaturization and large aperture design, so as to meet the miniaturization design of the optical lens and achieve better image quali...
