Industrial lenses are the starting point for the acquisition and transmission of information about the object under test in machine vision systems, and their quality directly affects the accuracy of the final image. Unlike ordinary surveillance lenses, machine vision lenses (FA lenses) must provide lower optical distortion, higher optical resolution, and a rich spectral selection to enable cameras to capture clear and sharp images to meet the application needs of vision systems in various situations. FA lenses, whether wide-angle, compact, or low-distortion, support various sensor sizes, from 2MP to 12MP and above, and offer a complete range of focal lengths from 8 to 75mm.
