Optical lens sets, camera modules and electronic equipment

Abstract

The application discloses an optical lens group, a camera module and electronic equipment, including a first lens with positive power, the object side of the first lens is convex at the near optical axis; a second lens with power, and the second lens The object side is convex at the near optical axis; the third lens has optical power; the fourth lens has optical power, the object side of the fourth lens is convex at the near optical axis, and the image side is concave at the near optical axis; The fifth lens has positive refractive power, the object side of the fifth lens is concave at the near optical axis, and the image side is convex at the near optical axis; the sixth lens has positive refractive power, and the object side of the sixth lens is convex at the near optical axis ; The seventh lens has negative refractive power, and the image side of the seventh lens is concave at the near optical axis. The present application designs an optical lens group composed of seven lenses, which can rationally distribute the distribution of the lenses in space to realize the compression of the total length of the lens group, thereby meeting the design requirements of ultra-thin and high-resolution.

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...
