Description

technical field [0001] The present application relates to the field of optical elements, and in particular to an optical lens and electronic equipment including the optical lens. Background technique [0002] In recent years, the auxiliary driving system of automobiles has been developed rapidly, and the on-board optical lens has played an irreplaceable role as the eyes of the car to obtain external information. In order to obtain information more accurately, the system needs to be equipped with a large chip with higher resolution, so the resolution requirements for the optical lens itself are getting higher and higher. In order to meet higher imaging quality requirements, more lens structures are often selected, but this will increase the cost and seriously affect the miniaturization of the lens. [0003] In addition, due to safety considerations, automotive optical lenses used in the field of autonomous driving have high requirements for stability and need to be able to c...
