Camera lens

Abstract

The invention discloses a camera lens, which comprises a first lens with negative focal power, a second lens with positive focal power, a third lens with positive focal power, a fourth lens with negative focal power, a fifth lens with positive focal power and a sixth lens with negative focal power from an object side to an image side in sequence, wherein the second lens has a convex image-side surface, and is made of glass; the third lens has a convex image-side surface; the sixth lens has a convex object-side surface and a concave image-side surface; and the camera lens meets a conditional expression that: -1.7<f2 / f4<-0.7, the f2 is an effective focal length of the second lens, and the f4 is an effective focal length of the fourth lens. The camera lens disclosed by the invention can effectively eliminate aberration, meet the demand of high pixels and reduce costs while guaranteeing miniaturization.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to a camera lens. Background technique [0002] With the development of science and technology, portable electronic products are gradually emerging, especially the portable electronic products with camera function are more favored by people. The photosensitive element of the optical imaging system includes two kinds of photosensitive coupling element (CCD) or complementary metal oxide semiconductor element (CMOS). With the development of semiconductor process technology, the pixel size of photosensitive elements is reduced, and the optical imaging system tends to have higher pixels and higher imaging quality. In order to meet this trend, high image quality, miniaturization, and wide-angle are further required for imaging lenses applied to portable electronic products. [0003] The current mainstream camera lens is generally composed of five lenses, and it is difficult to meet the requ...

AI Technical Summary

Problems solved by technology

[0003] At present, the mainstream camera lens is generally composed of five lenses, which is difficult to meet the requirements of higher imaging quality, so it is necessary to increase the number of lenses

However, the increase in the number of lenses is not conducive to the miniaturization of the camera lens, and the cost will increase accordingly
