Only a few dim lamps light the way as a guide leads visitors down a carved passageway into a former mine in New Jersey. The group stops when it reaches a spot called the Rainbow Tunnel. The guide turns off the overhead bulbs and flips on ones with invisible ultraviolet (UV) light. The once dull rock walls suddenly glow brilliant shades …
In forensic science, fluorecein (a common fluorescent dye) can be mixed with other chemicals and sprayed on surfaces at crime scenes to reveal blood splatter when UVA light is shone on the surfaces. UV can also cause other body fluids, bone fragments and sometimes fingerprints to fluoresce. UV fluorescence can be used as a security …

Emerald Village is the premier place for NC gem mining with real gem mines NC offering gem mine tours in North Carolina with black light tours.
Materials derived from the mines also caught the attention of collectors who were attracted to the fluorescent rocks for their beauty, rarity and because under ultraviolet light many of them emitted a colorful, fluorescent glow.
Fluorescence techniques are nondestructive analytical methods used in a wide range of applications. Since many fluorophores of interest can be excited with UV light and nowadays compact solid-state UV emitters are available, UV fluorescence methods are emerging. The chapter will give a survey of both fundamentals and applications of …

Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns.
Ultraviolet Lights. Ultraviolet (UV) Lights. Ultraviolet lights have a number of important applications in both residential and business settings. Some of the most common uses for ultraviolet light are to: Ultraviolet lamps come in a variety of shapes and sizes, depending on their intended use. Some are small and hand-held, while others are ...
Lightweight, IP 65 Rated 365nm, UV-365MSBLC UV-A inspection lamps can be used in nondestructive testing (NDT), nondestructive evaluation (NDE), forensics, and security inspections. The UVision 365 multi-LED Ultraviolet fluorescent blacklight inspection lamp is the best compact handheld lamp available. For fluorescent inspections, in harsh …
We're interested in the type of luminescence generated by the absorption of light - specifically ultraviolet light. This is called photoluminescence and is divided into two categories, fluorescence and phosphorescence. Typical fluorescent minerals include: aragonite, calcite, fluorite, powellite, scheelite, sodalite, willemite, and zircon.
Ultraviolet fluorescent tubes and lamps are specialist products that offer an ultraviolet output to a multitude of commercial and domestic applications including fly killer units, pond and air filtration, bank note detection, and many more. You will find blacklights, germicidal fluorescent lights, compact fluorescent lights and incandescent light …
Typical fluorescent lamps, including CFLs, which consumers would encounter, emit very low levels of UV. In order to measure any UV radiation from these lamps, very sensitive measuring equipment ...
The uVision 365 multi-LED Ultraviolet fluorescent blacklight inspection lamp is the best compact handheld lamp available. For fluorescent inspections, in harsh indoor and outdoor environments, the uVision 365 Series is available in twelve models to suit your specific needs – with five different UV-A intensity levels.
The emitted electrons collide with and excite the mercury atoms, resulting in the emission of ultraviolet radiation and a small amount of blue visible light. The inside of the discharge tube is coated with a mixture of fluorescent powders. The ultraviolet radiation is converted to visible light when it passes through the fluorescent powder …
The near UV light, also known as black light and UVA light, emits UV light of 315–400 nm. This lamp was invented in 1935 and this fluorescent lamp uses a phosphor on the inner glass surface of the tube which absorbs the visible light and allows the UVA light to go through.
PURITEC ® HNS ® UV-C Fluorescent Discharge lamps for Germicidal Purification, and UV-A lamps are available for applications ranging from Insect Traps to Scientific Analysis and Entertainment Blacklight Effects. Refer to our HBO and HXP product pages for information on broad spectrum lamps that offer output in the ultraviolet range.
Abstract. Photoreactivation of microorganisms following UV disinfection is one of the research topics of interest in assessing the performance of UV disinfection, because there is little consensus on how the visible light intensity relates to the photoreactivation rate and the maximum survival in wastewater treatment processes.
Ultraviolet lights are used for collecting and for illuminating displays of fluorescent specimens. They generally consist of a power supply, UV bulb, mechanical enclosure, and a UV filter. Bulbs and filters are selected for …
Investigation of the light emissions of some compact fluorescent lamps and incandescent lamps commercially available to the Iranian consumers found warm white lamps are suitable for homes usage, while daylight lamps can be used for offices rooms. Background: Some characteristics of lighting sources such as color properties and …
This blog post will list the current manufacturers of UV flashlights, along with links to info on tube based fluorescent mineral lights in case you decide that type of light is more suitable for your needs.
Ultraviolet radiation,that portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region. Its wavelengths are between 400 and 10 nanometers. Learn more about ultraviolet radiation.
About 15% of the 5,000 or so known mineral species are known to fluoresce under ultraviolet light. Others fluoresce under the influence of X-rays, an electron or proton beam, or even mechanical stress (e.g., when …
Ultraviolet (UV) lamps emit electromagnetic radiation with a wavelength between 10 nanometers (nm) and 400 nm, which is below the visible light spectrum. UV lamps have industrial uses in sterilization, geology, polymer and adhesive curing, and laboratory research and analysis, including biological analysis. UV lamps often use fluorescent …

Philips offers highly quality TL lamps emitting UV-A in a spectral distribution wavelength of between 315 to 380 nm. This makes these lamps suitable for various applications such as phototherapy, curing & Photocatalytic oxidation.
Common fluorescent minerals include: fluorite, aragonite, opal, apatite, calcite, sodalite, willemite.
The tubes are coated with fluorescent chemicals. When the current is switched on, the starting mechanisms at each end of the lamp produce electrons that excite the gases inside the tube and make them release ultraviolet (UV) radiation. This UV radiation hits the fluorescent coating, which produces light. The colour of the light produced depends ...
