Abstract

The invention relates to an optical lens, a camera module and electronic equipment. The optical lens comprises a diaphragm, a zoom lens group, a light deflection assembly and a compensation lens group which are sequentially arranged from an object side to an imaging surface in the direction of an optical axis, the optical axis forms a first optical axis section between the diaphragm and the light deflection assembly, and the zoom lens group is located on the first optical axis section; the optical axis forms a second optical axis section between the light deflection assembly and the compensation lens group; wherein the first optical axis section is different from the second optical axis section. As the diaphragm is closest to the object side and is located at the foremost end of the whole optical lens, when the size of the diaphragm is adjusted, the size of the diaphragm is not limited by the sizes of other components on the first optical axis section and is not limited by the size of a component located on the second optical axis section. Therefore, the size of the diaphragm can be allowed to be increased according to requirements, so that the light inlet amount and the diffraction limit of light rays are improved without being limited by the sizes of other components.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] In related technologies, an optical lens can be arranged in a camera module, and the camera module can be installed on an electronic device to provide the electronic device with a corresponding shooting function. Take mobile phones as an example of electronic equipment. At present, the telephoto camera module in mobile phones has achieved 10x optical zoom, and 5x periscope optical zoom has begun to be widely used. Users' demand for telephoto lenses is also increasing. The current optical zoom solution mainly relies on switching back and forth between camera modules with different focal lengths, and since the periscope is in front, the aperture (aperture) of the optical system is set behind the periscope, and the size of the aperture will be limited by the size of the mobile phone...
