Due to its speed, accuracy and repeatability, the vision system can inspect hundreds or even thousands of parts per minute on the production line. Built around the appropriate resolution of the camera, it easily checks the details of objects too small for the human eye. Human eyes are able to perceive radiation in the electromagnetic wavelength range from 390 to 770 nm. In contrast, cameras can pick up a much wider range of wavelengths. Some machine vision systems operate in the infrared (IR), ultraviolet (UV), or X-ray range. Industrial vision systems, compared to optical inspection, are more accurate, faster and are not exposed to fatigue, distraction or disease. As a result, they reduce the number of defective components, while also reducing the human labor required for quality control.
