Abstract

The invention relates to the technical field of optical lenses, and particularly relates to a 12mm prime machine visual lens comprising a first lens, a second lens, a third lens, a fourth lens, a diaphragm, a fifth lens, a sixth lens, a seventh lens, an eighth lens and a ninth lens of which the central axes are arranged on the same horizontal line. When object distance changes, air space from the ninth lens to an image plane changes, i.e. the first to the ninth lenses move forward and backward together, only optical back focal length changes and other space size does not change. With application of the aforementioned structure, the pixel value can reach five million pixels when the focal length is 12mm and the corresponding chip size is 2 / 3" so that the high-end product demand can be met, and optical transmission aperture can also be flexibly adjusted.

Description

technical field [0001] The invention relates to the technical field of optical mirrors, in particular to a 12mm fixed-focus machine vision lens. Background technique [0002] Machine vision is the use of machines instead of human eyes for measurement and judgment. The machine vision system refers to converting the ingested target into an image signal through a machine vision product (that is, an image capture device, which is divided into two types: CMOS and CCD), and sending it to a dedicated image processing system. The image system performs various calculations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the results of the discrimination. [0003] In recent years, with the rapid development of the microelectronics industry, machine vision systems with high resolution and high processing speed have been born continuously, which puts forward new requirements for the matching optical lenses. Ho...
