Problems solved by technology

First of all, optical lenses for autonomous driving require extremely high pixel requirements. On the basis of the original optical lenses for automotive applications, optical lenses for autonomous driving usually use 6, 7 or even more lenses in order to improve the resolution capability. structure, but this will seriously affect the miniaturization of the lens

Abstract

Disclosed are an optical lens and an imaging device including the optical lens. The optical lens may sequentially include a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens along the optical axis from the object side to the image side. Wherein, the first lens can have negative refractive power, and its object side is convex, and the image side is concave; the object side of the second lens can be concave, and the image side can be convex; the third lens can have positive refractive power, and its object The side is convex and the image side is concave; the fourth lens may have positive power and the object and image sides are convex; the fifth lens may have positive power and the object and image sides are convex; and the sixth Lenses can have negative optical power with a concave surface on the object side and a convex surface on the image side. According to the optical lens of the present application, at least one of beneficial effects such as high resolution, miniaturization, small front diameter, small distortion, low cost, and good temperature performance can be realized.

Description

technical field [0001] The present application relates to an optical lens and an imaging device including the optical lens, more particularly, the present application relates to an optical lens including six lenses and an imaging device. Background technique [0002] Thanks to the rapid development of automotive assisted driving systems in recent years, lenses have been more and more widely used in automobiles, and the pixel requirements for automotive optical lenses are getting higher and higher. At the same time, more and more companies have begun to study autonomous driving optical lenses. [0003] For safety reasons, the performance requirements of optical lenses for automotive applications are usually very high, while the performance requirements for optical lenses for autonomous driving are even stricter. First of all, optical lenses for autonomous driving require extremely high pixel requirements. On the basis of the original optical lenses for automotive application...
