How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight is becoming an invaluable tool in revealing hidden things toresearchers and investigators, and lay tradespeople in many occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing those 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 mysteries and secrets. A few of these secrets are intentionally hidden from plain view, including watermarks, plus 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 would have been necessary to generate the sufficiently powered black light for such applications. But the high luminous efficiency of recent LEDs permits strong, bright UV light in a flashlight easily locked in the palm of a single 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 concentrate the ultraviolet beam.
Let’s now examine a few of the many applications now utilizing this modern device.
In this particular high-tech society which our company is a part, proving the authenticity of government currency and documents has developed into a significant challenge. Precision counterfeiting is fairly sophisticated, requiring increasingly complicated countermeasures. Embedded watermarks and holographs are examples of such countermeasures.
Tellers in banks and clerks in stores often think it is a job necessity to examine for these particular embedded markings within the currency passed before them. They are doing so by means of a small UV LED flashlight, which in turn causes the markings to fluoresce. (In cases like this, the result is bright enough to not be masked by surrounding white light.) Within a similar manner, TSA personnel validate your passport or driver’s license.
A well known application for the ultraviolet LED flashlight is the detection of urine as well as other bodily fluids, both from humans and from animals. The amino acids and salts 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 where their pets have urinated. The fluorescence posseses an amber color. Restaurant inspectors utilize the lights to check on for rat infestation and food contamination. Hotel inspectors (and picky guests) examinesheets and carpets, and mattresses for cleanliness by means of an ultraviolet flashlight.
A novel application for blacklight flashlights is scorpion hunting. The Southwest is essentially overrun from the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to get in the daytime, and they scamper far from ordinary white-light flashlights. However the UV flashlight causes their exoskeletons to fluoresce inside a blue-green color, and also this makes their capture quite simple.
Gemologists analyze jewels to figure out their value. Often significant sums of money ride on the judgments, which are derived from whether or not the jewel has been heat-treated, has flaws, or 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 inside a unique way.
There are more applications we haven’t even mentioned. Naturally, the versatility in the LED ultraviolet blacklight flashlight broadens daily.
