Criteria as applied to machine vision.
For inspection of moving or non moving parts strobe lighting can offer unsurpassed advantages over other types of lighting.
This integrated light reduces shadowing and provides uniform illumination on matte objects.
The lens may cause the specular reflection to disappear completely.
