How an Ultraviolet Blacklight Flashlight Unveils Mysteries

The ultraviolet blacklight flashlight has become an excellent tool in revealing hidden things toresearchers and investigators, and lay tradespeople in numerous occupations. The blacklight flashlight shines ultraviolet (UV) light on substances with fluorescent properties, causing them 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 secrets and mysteries. Many of these secrets are intentionally hidden from plain view, like watermarks, and a few occur naturally, including the spectral properties of gemstones.

Prior to the recent developments in light emitting diode (LED) technology, a fairly bulky apparatus might have been required to generate the sufficiently powered black light for such applications. However the high luminous efficiency of recent LEDs permits strong, bright UV light inside a flashlight easily held in the palm of a single hand, rendering application implementation convenient and practical. As an example, Simon Flashlights sells a UV Blacklight Flashlight which 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 of which we are a part, proving the authenticity of government currency and documents has turned into a significant challenge. Precision counterfeiting is very sophisticated, requiring ever more complicated countermeasures. Embedded watermarks and holographs are types of such countermeasures.

Tellers in clerks and banks in stores often discover it a job necessity to check for these particular embedded markings in the currency passed before them. They are doing so by means of a small UV LED flashlight, that causes the markings to fluoresce. (In this instance, the result is bright enough to not be masked by surrounding white light.) Inside a similar manner, TSA personnel validate your passport or driver’s license.

A favorite application for that ultraviolet LED flashlight will be the detection of urine as well as 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 the out-of-way corners where their pets have urinated. The fluorescence has an amber color. Restaurant inspectors use the lights to examine for rat food and infestation contamination. Hotel inspectors (and picky guests) examinecarpets and sheets, and mattresses for cleanliness by way of an ultraviolet flashlight.

A novel application for blacklight flashlights is scorpion hunting. The Southwest is more or less overrun by the arthropods, and many residents are diligent about capturing them. Being nocturnal, scorpions are usually difficult to find throughout the day, and they also scamper from ordinary white-light flashlights. Nevertheless the UV flashlight causes their exoskeletons to fluoresce inside a blue-green color, which makes their capture quite easy.

Gemologists analyze jewels to determine their value. Often significant sums of cash ride on the judgments, which are derived from if the jewel has become 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 related to each kind of precious stone fluoresce in a unique way.

There are more applications we haven’t even mentioned. Naturally, the versatility from the LED ultraviolet blacklight flashlight broadens daily.
