How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight is becoming a great tool in revealing hidden points toresearchers and investigators, and lay tradespeople in a number of occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing those 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 secrets and mysteries. A few of these secrets are intentionally hidden from plain view, including watermarks, and some occur naturally, like the spectral properties of gemstones.
Before the recent developments in light emitting diode (LED) technology, a somewhat bulky apparatus would have been needed to generate the sufficiently powered black light for such applications. However the high luminous efficiency of contemporary LEDs permits strong, bright UV light inside a flashlight easily locked in the palm of merely one hand, rendering application implementation practical and convenient. For example, Simon Flashlights sells a UV Blacklight Flashlight which is powered by three AAA batteries and uses 14 small LEDs to focus the ultraviolet beam.
Let’s now examine a few of the many applications now using this modern device.
Within this high-tech society of 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 holographs and watermarks are examples of such countermeasures.
Tellers in banks and clerks in shops often discover it a job necessity to check for these particular embedded markings inside the currency passed before them. They do so by means of a small UV LED flashlight, that causes the markings to fluoresce. (In this case, the effect is bright enough not to be masked by surrounding white light.) In a similar manner, TSA personnel validate your passport or driver’s license.
A favorite application for your ultraviolet LED flashlight will be the detection of urine and 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 your out-of-way corners in which 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 more or less overrun by the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to find throughout the day, plus they scamper far from ordinary white-light flashlights. But 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 find out their value. Often significant sums of income ride on the judgments, which are based on whether or not the jewel continues to be 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 type of precious stone fluoresce in a unique way.
There are other applications we haven’t even mentioned. Needless to say, the flexibility of the LED ultraviolet blacklight flashlight broadens everyday.
