Problems solved by technology

At present, when the optical lens is designed in a small size, the assembly of the structure of the optical lens is the primary consideration. This is because, in order to meet the miniaturization design, the production and manufacture of the components of the optical lens are more difficult, which also leads to an increase in the difficulty of assembly. In turn, the overall manufacturing cost of the optical lens is higher, which is not conducive to the control

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module and an electronic device. Background technique [0002] In recent years, with the advancement of the technology industry and the continuous development of imaging technology, optical lenses for optical imaging are widely used in electronic devices such as smartphones, tablet computers, and cameras. In order to meet the requirements of thin and light design of electronic devices, the miniaturization design of optical lenses also poses challenges. At present, when the optical lens is designed for small size, the assembly of the structure of the optical lens is the primary consideration. This is because, in order to meet the miniaturization design, the production and manufacture of the components of the optical lens are more difficult, and at the same time, the assembly difficulty is also increased. As a result, the overall manufacturing cos...
