How an Ultraviolet Blacklight Flashlight Unveils Mysteries

The ultraviolet blacklight flashlight is becoming a great 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 these 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. A few of these secrets are intentionally hidden from plain view, including watermarks, and some occur naturally, like the spectral properties of gemstones.

Before the recent developments in light emitting diode (LED) technology, a relatively bulky apparatus would have been needed to generate the sufficiently powered black light for such applications. However 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. As an example, Simon Flashlights sells a UV Blacklight Flashlight that is certainly powered by three AAA batteries and uses 14 small LEDs to target 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 very sophisticated, requiring more and more complicated countermeasures. Embedded holographs and watermarks are examples of such countermeasures.

Tellers in banks and clerks in shops often discover it work necessity to check for such embedded markings within the currency passed before them. They actually do so by means of a small UV LED flashlight, which in turn causes the markings to fluoresce. (In cases like this, the effect is bright enough to not be masked by surrounding white light.) Within 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 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 where their pets have urinated. The fluorescence has an amber color. Restaurant inspectors make use of 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 more or less overrun by the arthropods, and lots of residents are diligent about capturing them. Being nocturnal, scorpions are very difficult to get during the day, plus they scamper far from ordinary white-light flashlights. But the UV flashlight causes their exoskeletons to fluoresce within a blue-green color, which makes their capture really simple.

Gemologists analyze jewels to figure out their value. Often significant sums of money ride on their own judgments, which are derived from whether 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 related to every type of precious stone fluoresce in a unique way.

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