Abstract

The invention relates to a coaxial light source integrated ultra-wide-angle industrial inner wall detection lens. A front group lens with positive focal power, a diaphragm and a rear group lens with positive focal power are sequentially arranged in the lens from an object plane to an image plane along a light incidence direction; a coaxial light source lens group perpendicular to the light source direction and the light incident direction is arranged between two adjacent lenses in the front group of lenses; the front group lens comprises three negative lenses and four positive lenses; the rear group lens comprises a negative lens and a positive lens. The lens is compact in structure and suitable for industrial product inner wall detection.

Description

technical field [0001] The invention relates to an ultra-wide-angle industrial inner wall detection lens integrated with a coaxial light source. Background technique [0002] The basic function of the lens is to achieve beam transformation (modulation). In the machine vision system, the main function of the lens is to image the target on the photosensitive surface of the image sensor. The quality of the lens directly affects the overall performance of the machine vision system. Reasonable selection And installing the lens is an important link in the design of the machine vision system. With the development of society, the application of industrial lenses is becoming more and more extensive. Therefore, the demand for an industrial lens with visual alignment is increasing. However, when the existing industrial lenses are used for the inspection of the inner wall of industrial products, the field of view is small, and because there is no light source inside the industrial produ...
