Abstract

The invention relates to the technical field of optical lenses and particularly relates to a lens combined structure. The lens combined structure comprises a first lens, a second lens, a third lens, a fourth lens, a diaphragm, a fifth lens, a sixth lens, a seventh lens and an eighth lens, center axes of which are positioned on the horizontal line, wherein the distance between the top of the front end surface of the eighth lens and the top of the rear end surface of the seventh lens is regulated between 0.1mm and 6mm. When the focal length is 25mm by virtue of the lens combined structure, the dimension of the corresponding chip is 2 / 3'', the pixel value of the lens combined structure can reach 5 millions of pixels, so that the high-end product needs are met, and the clear aperture of the lens combined structure can be flexibly regulated. Besides, the invention further discloses a machine visual lens with the lens combined structure.

Description

technical field [0001] The invention relates to the technical field of optical mirrors, in particular to a lens combination structure and a machine vision lens with the structure. 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 f...
