Abstract

The invention discloses an optical lens group, a camera module and electronic equipment, and the optical lens group comprises a first lens which has positive focal power, wherein the object side surface of the first lens is a convex surface near an optical axis; a second lens which has focal power, wherein the object side surface of the second lens is a convex surface near the optical axis; a third lens which has focal power; a fourth lens which has focal power, wherein the object side surface of the fourth lens is a convex surface near the optical axis, and the image side surface of the fourth lens is a concave surface near the optical axis; a fifth lens which has positive focal power, wherein the object side surface of the fifth lens is a concave surface near the optical axis, and the image side surface of the fifth lens is a convex surface near the optical axis; a sixth lens which has positive focal power, wherein the object side surface of the sixth lens is a convex surface near the optical axis; and a seventh lens which has negative focal power, wherein the image side surface of the seventh lens is a concave surface near the optical axis. By designing the optical lens group composed of seven lenses, the distribution of the lenses in the space can be reasonably distributed to realize the compression of the total length of the lens group, so that the design requirements of ultra-thinness and high resolution are met.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical mirror group, a camera module and electronic equipment. Background technique [0002] With the development and progress of science and technology, portable electronic devices such as smartphones are becoming more and more popular, and people have higher and higher requirements for lenses mounted on electronic products. As portable electronic products are gradually becoming smaller and thinner, the lens group mounted on them The total length is also limited, which increases the difficulty of lens design while ensuring the image quality. The photosensitive element of a general camera lens is a charge-coupled element or a complementary metal oxide semiconductor sensor. With the development of photosensitive element technology, the photosensitive element gradually develops into the field of high pixels, and the pixel size is getting smaller and smaller. T...
