Impact of UV LED technology to the fluorescent magnetic particle inspection (MPI) and penetrant inspection (FPI)

Abstract 

UV LED technology is about to completely substitute discharge bulb based UV sources in NDT.
UV LED Technology offer possibilities to NDT the industry never had before.

The new technology has a fundamental impact to the fluorescent inspection processes. This impact is bigger than any other development in this field since decades.

UV LED Technology can sustainable improve the inspection process performance, but it is also able to critically affect the process adversely.

This presentation will explain the physiology of the human vision, how the lamp characteristics affect the strain and performance of the inspector and how the inspection can be made better, easier and faster, while reducing the costs of the inspection.
