Problems solved by technology

Traditional imaging lenses generally do not have space to use a supporting member (spacer ring), and can only be directly supported by two lenses. However, such a direct bearing makes the lens lose its height, and the risk of separation is high, and there is a stress concentration on the assembled lens, which affects Image quality

Abstract

The invention relates to a spacing ring (1), an optical lens and a camera module. The spacing ring (1) is arranged in a lens cone of the camera module, and is used for spacing two adjacent lenses in the optical lens; the spacing ring (1) comprises a first surface (101) abutting against one of the lenses, a second surface (102) abutting against the other lens, as well as a third surface (103) connected with the inner wall of the lens cone; and the spacing ring (1) also comprises a fourth surface (104) which is far away from the third surface (103) and is used for avoiding the lenses in the optical lens. When the optical lens is assembled according to the spacing ring, the lenses can be avoided, each lens in the optical lens is provided with a boss, can provide a mounting space for the spacing ring and can avoid the spacing ring. Therefore, after the optical lens or the camera module is assembled, the stability is higher, the imaging quality is guaranteed, and the problem that the lens stress is concentrated is solved.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a spacer ring, an optical lens comprising the spacer ring and a camera module comprising the optical lens. Background technique [0002] In recent years, with the continuous advancement of science and technology, the popularization of personal electronic products and mobile communication products equipped with imaging devices such as mobile phones and tablet computers has led to the rise of miniaturized imaging lenses. Miniaturized imaging lenses with excellent imaging quality demand has also increased significantly. Traditional imaging lenses generally do not have space to use a supporting member (spacer ring), and can only be directly supported by two lenses. However, such a direct bearing makes the lens lose its height, and the risk of separation is high, and there is a stress concentration on the assembled lens, which affects Image quality. Contents of the invention [0003]...
