How an Ultraviolet Blacklight Flashlight Unveils Mysteries
The ultraviolet blacklight flashlight has become an invaluable tool in revealing hidden items 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 mysteries and secrets. A few of these secrets are intentionally hidden from plain view, including watermarks, plus some occur naturally, including the spectral properties of gemstones.
Prior to the recent developments in light emitting diode (LED) technology, a fairly bulky apparatus would have been needed to generate the sufficiently powered black light for such applications. But the high luminous efficiency of contemporary LEDs permits strong, bright UV light in a flashlight easily located in the palm of a single hand, rendering application implementation convenient and practical. 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 using this modern device.
Within 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 very sophisticated, requiring more and more complicated countermeasures. Embedded holographs and watermarks are types of such countermeasures.
Tellers in banks and clerks in stores often find it employment necessity to check 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 this case, the result 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 well known application for the ultraviolet LED flashlight is definitely the detection of urine along with other bodily fluids, both from humans and from animals. The black light doesn’t trigger fluorescence with any strength until the substances are deposited after the containing fluids have evaporated, even though the amino acids and salts suspended in these fluids possess fluorescent characteristics.
Cat owners use UV LED flashlights to ferret the out-of-way corners where their pets have urinated. The fluorescence comes with an amber color. Restaurant inspectors use the lights to check on 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 pretty much overrun from the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are very hard to find throughout the day, plus they scamper from ordinary white-light flashlights. Nevertheless the UV flashlight causes their exoskeletons to fluoresce in a blue-green color, and also this makes their capture quite easy.
Gemologists analyze jewels to figure out their value. Often significant sums of cash ride on the judgments, which derive from whether the jewel has become 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 every type of precious stone fluoresce inside 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.
