Optical lens, camera shooting module and electronic equipment

Abstract

The invention discloses an optical lens, a camera shooting module and electronic equipment. The optical lens comprises a focusing assembly, a first lens and a second lens which are sequentially arranged from an object side to an image side along an optical axis, wherein the focusing assembly comprises a focusing layer, the curvature radius of the focusing layer at the optical axis is a variable curvature radius, the first lens has positive refractive power, the second lens has positive refractive power, the optical lens meets the relational expression that the absolute value of Rly/Rlj is greater than 1 and less than 2.5, Rly is the curvature radius of the focusing layer at the optical axis in a far-focus state, and Rlj is the curvature radius of the focusing layer at the optical axis in a near-focus state. According to the optical lens, the camera shooting module and the electronic equipment provided by the invention, the curvature radius of the focusing assembly can be changed when objects with different object distances are shot while the light, thin and miniaturized design is met, so that incident light can be converged on the imaging surface of the optical lens, the optical lens is enabled to have high picture texture, resolution and imaging definition, and the high-definition imaging requirement of people on the optical lens 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] At present, with the wide application of electronic devices such as mobile phones, tablet computers, drones, and computers in daily life, people have higher and higher requirements for the imaging quality of optical lenses. achieve higher image quality. In order to achieve clear imaging and achieve higher imaging quality, the number of lenses in the optical lens is also increasing. Among them, the number of lenses required by the zoom optical lens is more, resulting in an increasing volume of the zoom optical lens, which is not conducive to The development trend of miniaturization and thinning of zoom optical lens. That is to say, under the design trend of thin, light and miniaturized optical lenses, it is difficult for optical lenses to image clearly, with poor image quality and lo...

In order to achieve clear imaging and achieve higher imaging quality, the number of lenses in the optical lens is also increasing. Among them, the number of lenses required by the zoom optical lens is more, resulting in an increasing volume of the zoom optical lens, which is not conducive to Development trend of miniaturization and thinning of zoom optical lens

That is to say, under the design trend of thin, light and miniaturized optical lenses, it is difficult for optical lenses to image clearly, with poor image quality and low resolution, and it is difficult to meet people's high-definition imaging requirements for optical lenses.
