Abstract

The invention discloses an optical lens and an electronic device comprising the same. The optical lens sequentially comprises, from an object side to an image side along an optical axis, a first lens with negative focal power; a second lens with positive focal power; a third lens with focal power; a fourth lens with focal power; and a fifth lens with positive focal power. The third lens and the fourth lens are cemented to form a cemented lens.

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 automotive assisted driving systems, optical lenses have become more and more widely used in automobiles, and users have higher and higher requirements for the pixel quality of automotive lenses. At the same time, based on safety considerations, the market has very high requirements for the performance of vehicle lenses. Of course, the requirements for the performance of vehicle lenses used in autonomous driving are more stringent. [0003] Autonomous driving in-vehicle footage requires extremely high pixel quality. In general, on the basis of the original vehicle lens, in order to improve the resolution capability of the optical lens for autonomous driving, a structure of six or more lenses is usually used, but this will seriously affect the m...
