Description

technical field [0001] The present application relates to the field of optical elements, and more specifically, to an optical lens and electronic equipment. Background technique [0002] In recent years, with the rapid development of automobile auxiliary driving systems, the application of optical lenses in automobiles has become more and more extensive. At the same time, users have higher and higher requirements for the imaging quality of vehicle lenses. In order to meet the application requirements of vehicle-mounted front-view lenses, more and more lens manufacturers have begun to study how to make vehicle-mounted front-view lenses with features such as miniaturization and high pixels. [0003] At present, in order to improve the resolution capability of the existing vehicle optical lens, most lens manufacturers usually increase the number of lenses to improve the resolution capability of the lens, but this will affect the miniaturization of the lens to a certain extent ...
