Abstract

The present application discloses an optical lens, and 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 positive refractive power; the second lens can have negative refractive power, its object side is convex, and the image side is concave; the third lens can have positive refractive power, its object side is concave, and the image side is concave a convex surface; the fourth lens may have positive power, and its object side and image side are convex; the fifth lens may have positive power, and its object side and image side are convex; and the sixth lens may have positive power, Both the object side and the image side are convex. According to the optical lens of the present application, at least one beneficial effect of high resolution, small distortion, small FNO, small chief ray angle, and strong thermal stability can be realized.

Description

technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including six lenses. Background technique [0002] Optical lenses are an important part of realizing unmanned driving. For some lenses for special applications, in order to collect more light, the lens FNO is generally required to be smaller. For some specific lenses, higher resolution is usually required for clear imaging. However, in general, the smaller the FNO, the blurrier the image, so it is difficult to achieve high resolution for a lens with a small FNO. [0003] The purpose of this application is to provide an optical lens capable of achieving high resolution in addition to the small FNO of the lens. Contents of the invention [0004] The present application provides an optical lens that is applicable to vehicle installation and can at least or partially overcome at least one of the above-mentioned defects in the ...
