How an Ultraviolet Blacklight Flashlight Unveils Mysteries

The ultraviolet blacklight flashlight has become a great 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. 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, like watermarks, and some occur naturally, such as the spectral properties of gemstones.

Prior to the recent developments in light emitting diode (LED) technology, a somewhat bulky apparatus might have been required to generate the sufficiently powered black light for these particular applications. Nevertheless the high luminous efficiency of recent LEDs permits strong, bright UV light within a flashlight easily located in the palm of one hand, rendering application implementation practical and convenient. For instance, 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 making use of this modern device.

In this high-tech society which our company is a part, proving the authenticity of government currency and documents has become a significant challenge. Precision counterfeiting is fairly sophisticated, requiring ever more complicated countermeasures. Embedded holographs and watermarks are types of such countermeasures.

Tellers in clerks and banks in shops often discover it 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 causes the markings to fluoresce. (In cases like this, the effect 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 favorite application for your ultraviolet LED flashlight will be the detection of urine and 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 salts and acids suspended in these fluids possess fluorescent characteristics.

Cat owners use UV LED flashlights to ferret out your 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) examinecarpets and sheets, and mattresses for cleanliness through an ultraviolet flashlight.

A novel application for blacklight flashlights is scorpion hunting. The Southwest is essentially overrun by the arthropods, and lots of residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to find throughout the day, and they also scamper away from ordinary white-light flashlights. Nevertheless the UV flashlight causes their exoskeletons to fluoresce in a blue-green color, which makes their capture quite simple.

Gemologists analyze jewels to determine their value. Often significant sums of money ride on the judgments, which derive from whether the jewel continues to be 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 associated with each kind of precious stone fluoresce within a unique way.

There are more applications we haven’t even mentioned. Needless to say, the flexibility in the LED ultraviolet blacklight flashlight broadens everyday.
