UV analysis lamp

The UV analysis lamp is a mains-powered UV analysis lamp with handle (for 120 V, 50 Hz). It is suitable for long- and short-wave UV light and is equipped with a special filter for both wavelength ranges. A tripod is available as an accessory.
In the gemmological field, UV lamps support identification by generating material-typical luminescence. A distinction is made between the two luminescence phenomena – fluorescence (not afterglow) and phosphorescence (afterglow).
Counterfeit banknotes and other important documents can also be easily identified using UV and analysis lamps. When objects are exposed to UV light, their fluorescent and phosphorescent areas are revealed. Bills, credit cards, driver’s licenses, passports and ID cards all have fluorescent markers. UV-sensitive ink and watermarks that are invisible under normal light are found on most passports. Banknotes often have images or colored fibers worked into the paper that are only visible under ultraviolet light.
