Machine vision lighting is defined as computerized light measurement.
- 90% of the success of any machine vision application is through proper lighting.
- Cameras do not see objects; they see the light reflected from objects towards them.
- The bottom line: Light allows the camera to SEE. If the camera can’t see the part or mark, it can’t be read and it can’t be inspected.
