How an Ultraviolet Blacklight Flashlight Unveils Mysteries

The ultraviolet blacklight flashlight is becoming a great tool in revealing hidden things toinvestigators and researchers, 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, like watermarks, plus some occur naturally, like the spectral properties of gemstones.

Prior to the recent developments in light emitting diode (LED) technology, a fairly bulky apparatus could have been required to generate the sufficiently powered black light for these particular applications. But the high luminous efficiency of recent LEDs permits strong, bright UV light in a flashlight easily located in the palm of one hand, rendering application implementation convenient and practical. For example, Simon Flashlights sells a UV Blacklight Flashlight which 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 making use of this modern device.

In this high-tech society of which we have been a part, proving the authenticity of government currency and documents has turned into a significant challenge. Precision counterfeiting is fairly sophisticated, requiring more and more complicated countermeasures. Embedded holographs and watermarks are examples of such countermeasures.

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

A novel application for blacklight flashlights is scorpion hunting. The Southwest is essentially overrun from the arthropods, and several residents are diligent about capturing them. Being nocturnal, scorpions are quite hard to find in the daytime, and they also 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 simple.

Gemologists analyze jewels to figure out their value. Often significant sums of income ride on their judgments, which are based on whether or not the jewel has been 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 type of precious stone fluoresce inside a unique way.

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