Optical lens

Abstract

The invention relates to an optical lens. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens, wherein the first lens has negative focal power, the object side surface of the first lens is a concave surface, and the image side surface of the first lens is a concave surface; and the first lens, the second lens, the third lens, the fourth lens and thefifth lens are sequentially arranged from the object side to the image side so as to form an optical lens with high resolution, small aperture and large camera shooting range. Meanwhile, the opticallens can meet a requirement of miniaturization.

Description

technical field [0001] The invention relates to an optical lens. Background technique [0002] The optical imaging system usually receives the imaging light reflected by the imaging object through the optical imaging lens to collect the imaging light, and the light collected by the optical imaging lens is subjected to photosensitization through the photosensitive chip, so as to realize the image acquisition of the object. With the development of science and technology, the requirements for the resolution of the lens are getting higher and higher, and different fields have different requirements for the lens. For example, the vehicle lens used in the automotive field, because it involves traffic safety, compared with ordinary industry applications, the resolution of the lens is higher. The requirements are more stringent. That is to say, the resolution requirements of the lens group of the vehicle lens are relatively high. [0003] On the other hand, due to the special appl...
