Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage. Fluorescent inspection is one of the commonly used NDT methods. The traditional UV light emitter is UV lamps, but it is bulky, uneconomical, and environmental damage.

The new technology is UV LED. GreatUV Corporation UV LED light sources are well used by the NDT customers. These light sources are: UV LED flashlights, UV LED headlamps, Multi-UV LED portable lamps, Multi-UV LED stationary lamps, and many more.
