Abstract

The invention discloses a pick-up lens group which sequentially comprises a first lens with focal power and an image side surface being a convex surface, a second lens having the positive focal power and the object side surface being a convex surface, a diaphragm, a third lens having focal power and the image side surface being a convex surface, a fourth lens having focal power and the object side surface being a concave surface, a fifth lens having focal power and the image side surface being a convex surface, a sixth lens having positive focal power and the object side surface being a convex surface, and a seventh lenshaving the negative focal power and the object side surface being a convex surface, and the image side surface being a concave surface. The lenses are arranged from an object side to an image side along an optical axis. The distance TTL from the object side surface of the first lens to the imaging surface of the pick-up lens group on the optical axis and the half ImgH of the diagonal length of an effective pixel area on the imaging surface meet the following condition: TTL / ImgH is less than 1.50.

Description

[0001] divisional application [0002] This application is a divisional application of the Chinese invention patent application submitted on January 15, 2020. technical field [0003] The present application relates to the field of optical elements, in particular, to a camera lens group. Background technique [0004] In recent years, camera lens sets for portable electronic products such as mobile phones have developed very rapidly. Camera lens sets for portable electronic products such as mobile phones with high pixels and large image areas have become standard configurations for portable electronic products such as mobile phones. Theoretically, the more lenses in the camera lens group, the stronger the ability to balance aberrations, and the better the imaging quality of the camera lens group can be greatly improved. However, the increase in the number of lenses will also increase the size of the lens, which is contrary to the development trend of ultra-thin and miniatur...
