LED linelights from SCHOTT enable large surface areas to be inspected at throughput speeds of several meters per second. These cast a thin stripe of light only several millimeters in width onto the area to be inspected. The illuminated area is then monitored by digital line cameras. The advantage is that, since the cameras only observe a thin stripe, the volume of data that needs to be processed is much lower than that of images that show the entire format. This enables higher throughput speeds.
