The invention discloses a macro industrial camera lens with high-resolution and low-distortion. The macro industrial camera lens comprises a front group of optical lens, a variable diaphragm and a rear group of optical lens which are orderly arranged in a lens structure along a light incidence direction; the focusing is accomplished by simultaneously moving six lens assemblies and the diaphragm, and the working distance is located at 50mm to 160mm; the low-distortion macro industrial camera lens is composed of a first convex lens, a second convex lens, a third concave lens, a glued optical lens formed by tightly bonding a fourth concave lens and a firth convex lens, and a sixth convex lens. The macro industrial camera lens disclosed by the invention is simple in structure, and the focusingis performed by adopting a way of moving the whole group so that the close shooting distance can reach 59mm, the distinct imaging is realized on closer object distance, the distortion is less than 0.05%, and the low-distortion equipment of the industrial camera lens is realized, and the macro industrial camera lens can be mated with the 1.1 high-resolution camera in 16:9 system.
Description
technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a high-resolution and low-distortion macro industrial lens. Background technique [0002] As industrial lenses are used more and more widely in the field of inspection applications, the lenses on the market cannot meet customer needs: high resolution, low distortion, macro distance, not only complex structure, but also inconvenient focusing, and close-up photography cannot be realized , it cannot achieve clear imaging at a closer object distance, nor can it meet the low distortion requirements of industrial lenses, and is not suitable for supporting use with 16:9 "1.1" high-resolution cameras. Contents of the invention [0003] The object of the present invention is to provide a high-resolution and low-distortion macro industrial lens, which not only has a simple structure, but also realizes focusing adjustments in different magnification ranges, so as to solve the...
