Problems solved by technology

However, the increase in the number of lenses increases the difficulty of processing and assembling the lenses, and increases the volume of the optical lens.
Therefore, in the related art, under the design trend of thin, light and miniaturized optical lenses, the image quality of optical lenses is poor, the resolution is low, and the imaging quality of optical lenses is not clear enough, it is difficult to meet people's high-definition requirements of optical lenses. imaging requirements

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 development of camera technology, people have higher and higher requirements for the imaging quality of optical lenses, which not only requires optical lenses to be thinner, lighter and smaller, but also to achieve higher imaging quality. In order to achieve higher imaging quality, optical lenses need to increase the number of lenses to correct aberrations. However, the increase in the number of lenses increases the difficulty of processing and assembling the lenses, and increases the volume of the optical lens. Therefore, in the related art, under the design trend of thin, light and miniaturized optical lenses, the image quality of optical lenses is poor, the resolution is low, and the imaging quality of optical lenses is not clear enough, it is difficult to mee...
