How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight is becoming a great tool in revealing hidden items toresearchers and investigators, and lay tradespeople in many occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing them 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. Some of these secrets are intentionally hidden from plain view, including watermarks, and a few 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 required 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 held 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 number of the many applications now utilizing this modern device.
In this particular high-tech society which we are a part, proving the authenticity of government currency and documents has developed into a significant challenge. Precision counterfeiting is quite sophisticated, requiring more and more complicated countermeasures. Embedded watermarks and holographs are examples of such countermeasures.
Tellers in clerks and banks in stores often think it is a job necessity to check on for these embedded markings inside the currency passed before them. They are doing so through a small UV LED flashlight, that causes the markings to fluoresce. (In cases like this, the impact is bright enough never to be masked by surrounding white light.) Inside a similar manner, TSA personnel validate your passport or driver’s license.
A popular application for your ultraviolet LED flashlight will be 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 the out-of-way corners in which their pets have urinated. The fluorescence posseses an amber color. Restaurant inspectors make use of the lights to check on for rat infestation and food contamination. Hotel inspectors (and picky guests) examinecarpets and sheets, and mattresses for cleanliness through an ultraviolet flashlight.
A novel application for blacklight flashlights is scorpion hunting. The Southwest is more or less overrun through the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are usually hard to find throughout the day, and they also scamper from ordinary white-light flashlights. However the UV flashlight causes their exoskeletons to fluoresce within 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 their judgments, which are derived 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 associated with every type of precious stone fluoresce inside a unique way.
There are other applications we haven’t even mentioned. Obviously, the versatility in the LED ultraviolet blacklight flashlight broadens everyday.
