Vision Inspection Systems Drive Profits

Lighting systems with adjustable intensity and specific angles enable in-line inspection of transparent, translucent, reflective, and opaque substrates. Three lights would be included in the configuration: a high-intensity top light for non-reflective and non-transparent surfaces; a low-intensity foil light for reflective surfaces and inks; and a back light, both illuminating and providing contrast for transparent or semi-transparent substrates. White LED temperature-controlled, actively cooled lamps offer longer life, more reliable consistency, and can even can be configured to illuminate color in the UV spectrum. Invisible inks are increasingly incorporated into packaging for anti-counterfeit or safety purposes.
