UV Light Technology - UV Fluorescence, UV fluorescent inspection

UV Fluorescence

We offer a wide range of UV-A blacklights - used by thousands of organisations worldwide for detection, validation and quality control in industrial, medical, scientific and public service applications.

We are widely recognised as world leaders in this field.

UV fluorescent inspection processes can be split into two categories...

...In conjunction with UV fluorescent materials or invisible/UV revealing materials.

Examples include:

NDT crack detection

Fluid leak detection

Material dispersion validation

Security mark detection

Smartwater detection

Scientific research

Special effects

Conformal coating validation

Hand washing technique validation

Detection of invisible / UV revealing markings

...Utilising the natural fluorescent properties of materials.

Examples include:

Detection of textile material mixes/contamination

Particulate microcontamination detection

Hydrocarbon contamination detection

Counterfeit detection

Revelation of forensic evidence

Revelation of conservation restorations and repairs

Detection of paper material mixes/contamination.

Conservation and preservation

Forensic science

Infection control

Detection of ringworm on animals

UV Fluorescence explained...

UV fluorescence requires a UV-A blacklight (also known as woods light). This represents a section of the electromagnetic spectrum of light which extends from the blue end of the visible (400nm) to the UV-A/UV-B boundary (315nm).

The excitation energy provided by UV light photons is much higher than the energy of thermal motion of the absorbing molecules (fluorescent pigments) at physiological temperatures. Consequently the absorbing molecules temporarily assume energy levels that otherwise they would never attain. As an excited electron returns to a lower energetic state, its excess energy is disposed of as a photon emission, resulting in fluorescence. Fluorescent light is recognised by its usually longer wavelength, compared with the exciting radiation.
