Abstract

The invention provides an optical lens and an image acquisition component. The optical lens comprises a reverse telephoto lens group and a rear lens group which are coaxially arranged in sequence from an object side to an image side, the reverse telephoto lens group comprises a first negative lens group and a second positive lens group which are arranged in sequence; the first negative lens group comprises at least one lens, and the second positive lens group comprises at least one lens; and the rear lens group includes at least one lens. According to the optical lens provided by the invention, the reverse telephoto lens group and the rear lens group are arranged, the reverse telephoto lens group is used for converging the incident light, so that the converged light enters the rear lens group, low distortion can be realized under the condition that the lens realizes a large field angle, and the image quality and the resolution of a shot target are ensured.

Description

technical field [0001] The application belongs to the technical field of optical devices, and in particular relates to an optical lens and an image acquisition component. Background technique [0002] With the development of computer vision technology, image acquisition components can be combined with robots. Image acquisition components act as the eyes of robots and can assist robots to complete work in specific industries. Taking industries such as manufacturing and logistics as an example, the combination of image acquisition components and robots can complete tasks such as palletizing, loading, and item grabbing. [0003] Image acquisition components generally include optical lenses, image sensors, and image processors. The design of optical lenses will directly affect the imaging quality, and the imaging quality will affect the working accuracy of the robot. In some application scenarios, such as object grabbing application scenarios, in the case of large objects, opti...
