Discription
UV analysis lamp
The UV analysis lamp is a Mains-powered UV analysis lamp with handle (for 230 V, 50 Hz). It is suitable for long-wave and short-wave UV light and is equipped with a special filter for both wavelength ranges. A stand is available as an accessory.
In the gemmological field, UV lamps support identification by generating luminescence typical of the material. A distinction is made between the two luminescence phenomena– fluorescence (not photoluminescent) and phosphorescence (photoluminescent).
UV and analysis lamps can also be used to easily identify forgeries of banknotes and other important documents. 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.
