Abstract

The invention discloses a lens group and a camera lens module. The lens group comprises a plurality of lenses which are coaxially arranged in sequence. The plurality of lenses include a first lens, asecond lens and a third lens. The second lens is clamped with the first lens, and the third lens is clamped with the first lens. According to the lens group and the camera lens module in the embodiment of the invention, the second lens and the third lens are each clamped with the first lens, optical axes of the lenses are easy to align, and only one integral tolerance exists between the lens groupand a lens barrel, so that the accumulated tolerance between the lenses and the lens barrel is greatly reduced, the assembly precision of the camera lens module is improved, and the quality of imagesshot by means of the camera lens module is improved.

Description

technical field [0001] The invention relates to optical imaging technology, in particular to a lens group and a lens module. Background technique [0002] With the development of multimedia technology, electronic products with camera function are more and more favored by consumers. While people are pursuing the miniaturization of electronic products, they put forward higher requirements for the quality of the images they shoot. The image is clear. However, it is difficult to align the multiple lenses of the current lens module with the optical axis during packaging, and there will be a eccentricity tolerance between each lens and the lens barrel, and the tolerance of the entire lens module is caused by the tolerance of each lens Accumulatively, the assembly accuracy of the lens module is low, which in turn affects the quality of the captured image. Contents of the invention [0003] Embodiments of the present invention provide a lens group and a lens module. [0004] Th...
