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, and people's requirements for the pixels of automotive lenses are also getting higher and higher. Because the lens of self-driving cars has extremely high requirements on pixels. 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 6-piece or more lens structure, but this will seriously affect the miniaturization of the lens . [0003] This type of optical lens also has high requirements for stability, and requires small changes in image height in high and low temperature environments to avoid lens performance degradation due to temp...
