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 and a fifth lens which are sequentially arranged along an optical axis from an object side to an image side; the first lens has positive refractive power and has an object-side surface being convex in a paraxial region thereof; the second lens has negative refractive power and has an image-side surface being concave in a paraxial region thereof; the third lens, the fourth lens and the fifth lens have refractive power, the image-side surface of the fifth lens is a concave surface in a paraxial region thereof, the optical lens meets the following relational expression: ImgH / ObjH is more than 0.4 and less than 1.2, ImgH is the radius of the maximum effective imaging circle of the optical lens, and ObjH is half of the height of an object corresponding to the maximum effective imaging circle of the optical lens. The optical lens, the camera module and the electronic equipment provided by the embodiment of the invention have relatively large effective focal length and magnification while realizing miniaturization, and can realize clear shooting of local detail information of an object in a range of 5mm to 20mm.

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 rapid development of science and technology, the application of small electronic devices (such as mobile phones, tablet computers, telephone watches, etc.) is becoming more and more popular, and their functions are becoming more and more diversified, especially the requirements for camera functions are more diverse. At present, in order to meet people's increasing camera requirements, most electronic devices adopt different configurations such as long focal length, wide angle, large aperture, and macro to meet different usage needs. [0003] Under the development trend of miniaturization and thinning of smart phones, correspondingly, the camera also needs to meet the requirements of miniature design. However, the miniature design of the camera has problems such as poor macro ...
