Abstract

The invention relates to an f16mm high-definition low-distortion semi-group mobile industrial lens. The lens comprises a main lens cone, a front group of lenses, an iris diaphragm and a rear group of lenses, wherein a front group lens cone and a rear group lens cone connected to a rear side of the front group lens cone are arranged in the main lens cone; a rear end of the main lens cone is provided with a connection seat; the front group of lenses is successively installed in the front group lens cone along a light incident direction; the iris diaphragm is installed in the rear group lens cone; and the rear group of lenses is installed in the rear group lens cone and the connection seat. The front group of lenses is formed by a first negative crescent lens, a first double convex lens, a second double convex lens and a first agglutination group connected to a first double concave lens in a sealing mode. The rear group of lenses is formed by a second double concave lens, a second agglutination group connected to a third double convex lens in the sealing mode, a fourth double convex lens, a positive crescent lens and a third agglutination group connected to a second negative crescent lens in the sealing mode. The main lens cone is provided with a diaphragm adjusting mechanism and a backseat lens cone is provided with a micro-focusing mechanism. The structure of the mobile industrial lens is simple and distortion of shooting to a close object is less than 1.1%.

Description

technical field [0001] The invention relates to a f16mm high-definition low-distortion half-group mobile industrial lens. Background technique [0002] The industrial lens is an important part of the machine vision system design as a component that places the imaging target on the photosensitive surface of the image sensor. However, the f16mm industrial lens currently on the market has begun to fail to meet the existing market demand due to shortcomings such as unclear field of view edge, large distortion, poor process performance, and high material cost. Contents of the invention [0003] The purpose of the present invention is to provide a f16mm high-definition low-distortion semi-group mobile industrial lens, which not only has a simple structure, but also can achieve a distortion of less than 1.1% for shooting close-up scenes. [0004] The technical solution of the present invention is: a f16mm high-definition low-distortion semi-group mobile industrial lens, includin...
