Robots or any part of an automated production line with a camera typically has a light as well to either see in low light conditions or to ensure it always sees with a similar amount of light hitting the lense.
Also, a lot of the machine vision systems I’ve run up against use red light, but it is kind of complex. If they want to detect say blood, I think blue light would actually give better contrast for detection.
