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] With the rapid development of automotive assisted driving systems in recent years, lenses have been more and more widely used in cars, especially for cars with assisted driving functions. Components, will affect the safety of driving. Therefore, the market has very high requirements for the performance of the front-view lens. [0003] On the one hand, people have higher and higher requirements for the pixels of car lenses. Therefore, on the basis of the original vehicle optical lens, in order to improve the resolution capability of the optical lens used in self-driving cars, people usually choose a 7-element or more lens structure, but this will seriously affect the miniaturization of the lens . [0004] On the other hand, because the car will drive in various environments, for example, ...
