Abstract

The invention discloses an optical lens, a camera module and electronic equipment, and the optical lens comprises,in order from an object side to an image side along an optical axis,a first lens element with positive refractive power, whereinan object-side surface and an image-side surface of the first lens element lens element are convex and concave in a paraxial region; a second lens element with positive refractive power, wherein an object-side surface and an image-side surface of the second lens element are convex in a paraxial region. a third lens element with negative refractive power; a fourth lens element with refractive power, wherein a concave image-side surface of the fourth lens element is in a paraxial region. a fifth lens element with negative refractive power, wherein both the object-side and image-side surfaces thereof are concave in a paraxial region; and a sixth lens element with positive refractive power, wherein the optical lens satisfies the following relational expression: FOV / TTL is greater than 1 deg / mm and less than 4 deg / mm. According to the optical lens, the camera module and the electronic equipment provided by the embodiment of the invention, high-quality imaging of distant sceneries can be realized while the design requirement of miniaturization is met.

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] As the public's miniaturization requirements for electronic equipment (such as mobile phones, tablet computers, telephone watches, etc.) The camera function of the electronic equipment, the camera module is an indispensable component in the existing electronic equipment. In order to meet the demand for miniaturization of electronic equipment, the size of the camera module tends to be more miniaturized. Due to the limitation of the thickness of the electronic equipment, the size of the camera module is relatively large, the camera module cannot achieve high-quality imaging, and at the same time, the camera module cannot achieve a clear imaging effect on distant objects. Contents of the invention [0003] The embodiment of the invention discloses an optical lens, a camera module, an...
