An ultraviolet light, informally called a black light, is a lamp or torch designed to show light that is part of the invisible light spectrum, that is, not seen by the naked human eye. Ultraviolet light is present in many light sources, but black lights use filters to cut down on the amount of visible light being emitted. This is important for making certain kinds of observations, such as being able to see florescence. In antiquing, black lights are used for such things as authenticating oil paintings, and for detecting uranium glass, areas of damaged and restoration on items, and counterfeit money.
In addition, antiques can be marked with fluorescent inks for security purposes. These markings are not visible to the naked eye but will show up under black light.
