Vision inspection industrial lens parameters and selection

In the machine vision system, the main function of the industrial lens is to image the target on the photosensitive surface of the image sensor, which has a great influence on the quality of product detection and imaging, and is an indispensable and important part of the machine vision detection system. Today, I will give you a brief introduction to the importance of industrial lenses in the machine vision system. In the machine vision system, the industrial lens plays the role of the eye, and feeds back the product detection situation to the industrial camera. The industrial lens is a high-performance resolution lens. The ultra-low distortion design technology is adopted to reduce the distortion rate and reflect the image effect more realistically. . Because the distortion technology can effectively reduce the reflection loss of the lens, reduce glare, increase the contrast, effectively improve the color reproduction, and improve the clarity of the image. The use of the combination of industrial lenses and industrial cameras has greatly improved the efficiency and effectiveness of industrial manufacturing. Industrial lenses are divided into long focal length, short focal length, and zoom lenses according to the detection requirements and measurement objects; according to the magnification of the lens, they can be divided into fixed magnification lenses, manual zooming, manual fine-tuning, fixed-frame fixed-magnification zooming, and electric Variable magnification lens; According to the different resolution, it can be divided into 5 million pixel and 1000 pixel lens. In addition, there is a telecentric lens that can well meet the high requirements for lens distortion in machine vision. It uses a unique parallel optical path design technology and has the characteristics of high resolution, large depth of field, and low distortion. It is very suitable for application Machine vision equipment. Industrial lens used in machine vision inspection system can be used to locate and detect objects with extremely high reflectivity, such as: surface scratch detection of metal, glass, film, wafer, etc., damage detection of chips and silicon wafers, MARK point positioning, glass Industrial precision alignment, positioning, part confirmation, dimension measurement, industrial microscopy and other CCD visual alignment, measuring devices and other fields such as slicer, dispenser, SMT inspection, plate mounter, etc., have a lot of market development space.
