High-pixel small-size optical system and camera module applying same

Abstract

The embodiment of the invention discloses a high-pixel small-size optical system, which sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seven lens, an eighth lens and a ninth lens from an object plane to an image plane along an optical axis, wherein the object plane sides of the first lens and the second lens are convex, the image plane sides of the first lens and the second lens are concave, and the focal power is negative; the object plane sides of the third lens and the sixth lens are convex surfaces, and the focal power of thethird lens and the sixth lens is positive; the image surface side of the fourth lens is a concave surface, and the focal power is negative; the image surface side of the fifth lens is a convex surface, and the focal power of the fifth lens is positive; the object plane side of the seventh lens is a convex surface, the image plane side of the seventh lens is a convex surface, and the focal power ispositive; the object plane side of the eighth lens is a concave surface, the image plane side of the eighth lens is a convex surface, and the focal power is negative; and the object plane side of theninth lens is a concave surface, and the focal power of the ninth lens is negative. On the other hand, the embodiment of the invention further provides a camera module. The optical system is mainly composed of nine lenses, the number of the lenses is reasonable, the structure is ingenious, the size is small, and the weight is light.

Description

Technical field: [0001] The invention relates to an optical system and a camera module for its application, in particular to a high-pixel and small-volume optical system and a camera module for its application. Background technique: [0002] With the increasing application of high-resolution technology, especially the wide application of high-pixel lenses, a series of similar lens products have appeared on the market, but they have the defects of large number of lenses, large volume, small target surface, and insufficient pixels. . Invention content: [0003] In order to overcome the problems of large number of lenses and large volume in existing high-pixel lens products, the embodiments of the present invention provide a high-pixel and small-volume optical system on the one hand. [0004] A high-pixel and small-volume optical system, which sequentially includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, and a fi...
