Abstract

The invention discloses a lens. The lens comprises a lens barrel; at least one lens, wherein the lens is arranged in the lens barrel; a focusing assembly, arranged on the object side of the lens barrel, or the focusing assembly and the lens BEING arranged in the lens barrel at intervals in the optical axis direction, or the focusing assembly being arranged on the image side of the lens barrel, andthe focal length of the focusing assembly changing after the focusing assembly is powered on. The focusing assembly is arranged on the object side, in the lens barrel or on the image side of the lensbarrel, after the focusing assembly is powered on, the curvature radius of the focusing assembly is adjusted, the focal length of the focusing assembly can be changed, deflection of light can be changed, optical focusing can be achieved, the whole imaging surface is clear and uniform, and compared with focusing of a voice coil motor, optical focusing is faster, an image surface is clearer, and focusing is more stable and smoother.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a lens, an imaging module and an electronic device. Background technique [0002] In the prior art, the automatic focusing of the lens usually uses a motor to move the lens in a physical way to achieve the best imaging effect. However, for sensitive lenses, such as macro lenses, the physical focusing method is not clear enough, and the stability is poor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a lens that can change the deflection of light to achieve optical focusing, thereby making the image plane clearer and focusing more stable and smooth. [0004] The present invention further proposes an imaging module. [0005] The present invention further provides an electronic device. [0006] The lens according to the present i...
