How an Ultraviolet Blacklight Flashlight Unveils Mysteries

The ultraviolet blacklight flashlight is becoming an excellent tool in revealing hidden things toresearchers and investigators, and lay tradespeople in a number of 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 mysteries and secrets. A few of these secrets are intentionally hidden from plain view, like watermarks, and some occur naturally, including the spectral properties of gemstones.

Ahead of the recent developments in light emitting diode (LED) technology, a somewhat bulky apparatus might have been necessary to generate the sufficiently powered black light for these 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 convenient and practical. For instance, 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 utilizing this modern device.

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

Tellers in clerks and banks in shops often find it a job necessity to examine for these embedded markings within the currency passed before them. They actually do so by means of a small UV LED flashlight, which causes the markings to fluoresce. (In this instance, 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 popular application for your ultraviolet LED flashlight is 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 the out-of-way corners by which their pets have urinated. The fluorescence comes with an amber color. Restaurant inspectors use the lights to examine for rat infestation and food contamination. Hotel inspectors (and picky guests) examinesheets and carpets, and mattresses for cleanliness through an ultraviolet flashlight.

A novel application for blacklight flashlights is scorpion hunting. The Southwest is pretty much overrun through the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to find in the daytime, plus they scamper away from ordinary white-light flashlights. Nevertheless the UV flashlight causes their exoskeletons to fluoresce in a blue-green color, and this makes their capture really simple.

Gemologists analyze jewels to figure out their value. Often significant sums of cash ride on their judgments, which are derived from whether the jewel has become heat-treated, has flaws, or is synthetic. Traditionally their work has required expensive laboratory equipment, but an LED ultraviolet flashlight has proved to be remarkably reliable for this work, particularly for preliminary analyses. The imperfections associated with each kind of precious stone fluoresce inside a unique way.

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