Fluorescence is light, The absence of heat source the light) , including specific material in light or other forms of electromagnetic radiation, under the stimulus of visible light. Interesting facts! Fluorescence is named after the rock! Ultraviolet (uv) for laboratory every day, the doctor's office, forensic crime scene investigation and critical infrastructure non-destructive evaluation of numerous applications.

the following is a short list of many special applications use ultraviolet: arson fire inspectors can actually see the promoter is not the consumption of fire residues. Under ultraviolet light, wall, floor, furniture and carpet chemical fuel carbon residue immediately visible. Art check uv react differently with different materials. Using ultraviolet light, collectors can protect themselves from art fraud.

Air, oil and gas industry, mining, welding, manufacturing plants and military department check to use nondestructive testing technology to examine all critical infrastructure. Pest control/food and agriculture: in order to determine the existence of rodents, inspectors with ultraviolet wavelengths of light lit up the related area. Rodent urine and hair is blue and white glow, easily when food bag or mixed with food grain identified. In addition, the mold on some grain will also fluoresce. Again into the validation: security experts need to track visitors and guests in a public place, including party, theme park, racetrack, concerts, stadiums, clubs, bazaar, theatre and similar places, as well as the polling station, swimming pool and private club.
