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

Abstract

A camera lens is provided. The camera lens includes, in sequence from an object side to an image side: a first lens having a negative refractive power; a second lens having a positive refractive power, an image-side surface of the second lens being configured as a convex surface and material of the second lens being glass; a third lens having a positive refractive power; a fourth lens having a negative refractive power; a fifth lens having a positive refractive power; and a sixth lens having a negative refractive power, an object-side surface of the sixth lens being configured as a convex surface and an image-side surface of the sixth lens being configured as a concave surface.

Description

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