How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight has become a great tool in revealing hidden items toinvestigators and researchers, and lay tradespeople in a number of occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing them to glow. If not entirely masked, when white light is present, these substances are otherwise invisible to the naked human eye, and in fact the fluorescent effect is greatly reduced.

An ultraviolet blacklight flashlight thus unveils secrets and mysteries. Many of these secrets are intentionally hidden from plain view, such as watermarks, and some occur naturally, including the spectral properties of gemstones.
Ahead of the recent developments in light emitting diode (LED) technology, a somewhat bulky apparatus would have been required to generate the sufficiently powered black light for these particular applications. But the high luminous efficiency of contemporary LEDs permits strong, bright UV light within a flashlight easily locked in the palm of merely one hand, rendering application implementation practical and convenient. As an 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 a number of the many applications now making use of this modern device.
In this high-tech society in which our company is a part, proving the authenticity of government currency and documents has become a significant challenge. Precision counterfeiting is quite sophisticated, requiring more and more complicated countermeasures. Embedded watermarks and holographs are samples of such countermeasures.
Tellers in banks and clerks in shops often find it employment necessity to check for these particular embedded markings in the currency passed before them. They actually do so by means of a small UV LED flashlight, that causes the markings to fluoresce. (In this instance, the result is bright enough to not be masked by surrounding white light.) In a similar manner, TSA personnel validate your passport or driver’s license.
A popular application for your ultraviolet LED flashlight is definitely 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 the out-of-way corners by which their pets have urinated. The fluorescence posseses an amber color. Restaurant inspectors make use of the lights to examine for rat food and infestation contamination. Hotel inspectors (and picky guests) examinecarpets and sheets, and mattresses for cleanliness by means of an ultraviolet flashlight.
A novel application for blacklight flashlights is scorpion hunting. The Southwest is more or less overrun through the arthropods, and lots of residents are diligent about capturing them. Being nocturnal, scorpions are quite difficult to find during the day, and they scamper away from ordinary white-light flashlights. Nevertheless the UV flashlight causes their exoskeletons to fluoresce within a blue-green color, and this makes their capture quite simple.
Gemologists analyze jewels to find out their value. Often significant sums of cash ride on their own judgments, which derive from whether the jewel has become heat-treated, has flaws, or possibly 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 related to each kind of precious stone fluoresce within a unique way.
There are other applications we haven’t even mentioned. Naturally, the flexibility from the LED ultraviolet blacklight flashlight broadens daily.
