Back Lights




Back Lighting provides an area of uniform illumination which when oriented behind the object of interest it can be used to create a part silhouette of instant contrast between dark and light. It is most useful for edge detection, part location/orientation or presence/absence, hole detection and object gauging. Linear back lights can also be deployed behind a moving web of material when used in conjunction with line scan cameras, when intensities are enough to freeze motion.
