Optical lens and imaging equipment

Abstract

The invention discloses an optical lens and imaging equipment comprising the optical lens. The optical lens can sequentially comprise a first lens, a second lens, a third lens, a fourth lens and a fifth lens from the object side to the image side along the optical axis, wherein the first lens can have negative focal power, and the object side surface and the image side surface of the first lens are concave surfaces; the second lens can have negative focal power, the object side surface of the second lens is a convex surface, and the image side surface is a concave surface; the third lens can have positive focal power, and the object side surface and the image side surface of the third lens are convex surfaces; the fourth lens can have positive focal power, and the object side surface and the image side surface of the fourth lens are convex surfaces; and the fifth lens can have negative focal power, and the object side surface and the image side surface of the fifth lens are concave surfaces. According to the optical lens provided by the invention, at least one of the beneficial effects of high resolution, miniaturization, large angular resolution, small aperture, long back focus, low cost and the like 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 five lenses and an imaging device. Background technique [0002] Thanks to the rapid development of automotive assisted driving systems in recent years, optical lenses have been more and more widely used in automobiles, and the pixel requirements for optical lenses for automotive applications are also getting higher and higher. [0003] The rapid development of the optical lens technology market for vehicle applications has enabled optical lenses to be applied in many frontier fields of society, and more and more optical lenses are used in vehicle front-view lenses for AR augmented virtual reality applications. For safety reasons, the performance requirements of optical lenses for automotive applications are usually very high, while the performance requirements for optical l...

AI Technical Summary

Problems solved by technology

First of all, the resolution requirements of optical lenses are getting higher and higher, and the total length of the system is often sacrificed in order to improve the resolution, which is also contrary to the miniaturization trend of optical lenses used in autonomous driving, and will also greatly increase the cost; Optical lenses require larger apertures for clear recognition in low-light environments

In addition, conventional forward-looking lenses are generally used to detect long-distance and azimuth objects in the front, and the field of view of the lens is relatively small.
