How an Ultraviolet Blacklight Flashlight Unveils Mysteries

The ultraviolet blacklight flashlight has become an excellent tool in revealing hidden things toinvestigators and researchers, and lay tradespeople in a number of occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing these to glow. These substances are otherwise invisible to the naked human eye, and in fact the fluorescent effect is greatly reduced, if not entirely masked, when white light is present.

An ultraviolet blacklight flashlight thus unveils mysteries and secrets. Some of these secrets are intentionally hidden from plain view, including watermarks, and some occur naturally, such as the spectral properties of gemstones.

Prior to the recent developments in light emitting diode (LED) technology, a relatively bulky apparatus might have been required to generate the sufficiently powered black light for such applications. But the high luminous efficiency of contemporary LEDs permits strong, bright UV light within a flashlight easily locked in the palm of one hand, rendering application implementation practical and convenient. For example, Simon Flashlights sells a UV Blacklight Flashlight that is powered by three AAA batteries and uses 14 small LEDs to target the ultraviolet beam.

Let’s now examine some of the many applications now using this modern device.

In this high-tech society in which we have been a part, proving the authenticity of government currency and documents has developed into a significant challenge. Precision counterfeiting is very sophisticated, requiring ever more complicated countermeasures. Embedded watermarks and holographs are samples of such countermeasures.

Tellers in banks and clerks in shops often find it work necessity to check on for such embedded markings in the currency passed before them. They do so through a small UV LED flashlight, which in turn causes the markings to fluoresce. (In this instance, the effect is bright enough never to be masked by surrounding white light.) Within a similar manner, TSA personnel validate your passport or driver’s license.

A well known application for your ultraviolet LED flashlight is the detection of urine as well as other bodily fluids, both from humans and from animals. The amino salts and acids suspended in these fluids possess fluorescent characteristics, although the black light doesn’t trigger fluorescence with any strength until the substances are deposited after the containing fluids have evaporated.

Cat owners use UV LED flashlights to ferret out the out-of-way corners in which their pets have urinated. The fluorescence has an amber color. Restaurant inspectors make use of the lights to examine for rat food and infestation contamination. Hotel inspectors (and picky guests) examinesheets and carpets, and mattresses for cleanliness by way of an ultraviolet flashlight.

A novel application for blacklight flashlights is scorpion hunting. The Southwest is pretty much overrun from the arthropods, and many residents are diligent about capturing them. Being nocturnal, scorpions are usually difficult to find in the daytime, and they also scamper away from ordinary white-light flashlights. However the UV flashlight causes their exoskeletons to fluoresce in a blue-green color, which makes their capture quite easy.

Gemologists analyze jewels to find out their value. Often significant sums of cash ride on the judgments, which derive from if the jewel continues to be heat-treated, has flaws, or perhaps is synthetic. An LED ultraviolet flashlight has proved to be remarkably reliable for this work, particularly for preliminary analyses, even though traditionally their work has required expensive laboratory equipment. The imperfections connected with each kind of precious stone fluoresce in a unique way.

There are other applications we haven’t even mentioned. Needless to say, the versatility in the LED ultraviolet blacklight flashlight broadens everyday.
