The luminescence sensors emit ultraviolet (UV) light and receive visible light reflected from luminescent surfaces. This technology allows the detection of fluorescent marks (even invisible to the human eye) on any object independently from its material, colour or distance inside the operating range. Moreover, it avoids light interferences or reflections from non-luminescent surfaces, like glass, mirrors, shiny metal surfaces, etc.
Luminescence sensors can satisfy many different applications, as for example in pharmaceutical and cosmetic industries to detect labels on glass phials or bottles, or correct medicine packaging, in woodworking and ceramic tiles production to check fluorescent selection marks; in automatic packaging to detect whitened paper or fluorescent glues, in textile industry to identify fluorescent cutting guides or labels; in mechanical industry to verify fluorescent paints, lubricants, gaskets or fittings; in vending machines or cash dispensers to check banknotes and credit cards.
