Inspection Lamps
UV-A Inspection lighting is used in Non-Destructive Testing (NDT) for fluorescing fluorescent magnetic inks and fluorescent liquid dye penetrants. UV-A light (also called black light) with a peak wavelength of 365nm used in darkened environments creates the optimal viewing conditions.
Johnson & Allen manufacture a range of both mains and battery powered handheld 365nm UV-A lamps, overhead lights and flashlight torches for NDT, crime scene forensics and document inspection.
