Abstract

The invention discloses an optical lens. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in sequence from an object side to an imageside along an optical axis, wherein the first lens has negative focal power with the object side surface being a convex surface and the image side surface being a concave surface; the second lens hasnegative focal power with the object side surface being a concave surface and the image side surface being a convex surface; the third lens has positive focal power with the object side surface beinga convex surface and the image side surface being a concave surface; the fourth lens has positive focal power with the object side surface and the image side surface being convex surfaces; the fifth lens has negative focal power; and the sixth lens has positive focal power.

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] With the continuous development of technology, people have higher and higher requirements for the resolution of optical lenses. However, with the improvement of resolution, the overall length and weight of the corresponding lens will increase, and the contradiction between lens resolution and miniaturization becomes increasingly prominent. [0003] In addition, lenses that need to be used in outdoor environments, such as vehicle lenses, are often in complex and changeable environments such as hot and dry, humid and rainy, cold, rainy and snowy, etc. Maintain a stable working resolution. In particular, such as vehicle front-view lenses that involve active safety of the driver, it is hoped that the influence of temperature on the imaging effect of the lens can be minimized to e...
