UV radiation is an invisible electromagnetic radiation in the wave length range from 100 nm to 400 nm. This range is divided into the sub-ranges UV-A, UV-B and UV-C. UV radiation is applied in various areas of industry, science and medicine, food industry, textile industry, mineralogy, forensics. Moreover, UV radiation is applied in the field of spectroscopy, X- ray microscopy, nanoscopy, photo lithography as well as for disinfecting and for polymerisation of synthetic materials, lacquers, glues etc. Notably s are used in NDT for excitation of inspection media fluorescence. Testing is carried out applying UV-A radiation (315 to 400 nm) with nominal maximum radiation intensity at. On the surface to be inspected the irradiation intensity must be larger than 1,000 ambient illumination of less than 20 lx. W/cm² at Nowadays, beside state-of-the-art UV LED lamps (page 48) the conventional low-pressure, medium-pressure and highpressure metal-halide lamps are also used in all kinds of industrial applications. Normally those are mercury gasdischarge lamps with/without additional doping elements such as gallium, indium, iron and lead. The figures below show examples of the spectral irradiation intensity of two common medium-pressure mercury gasdischarge lamps with optical filters: left without doping, right with Fe-doping. Radiation intensity µw/cm² Radiation intensity µw/cm² Wave length (nm) Helling mercury-vapour lamps are equipped with special UVbandpass filters und UVB-edge filters. Thus, harmful emissions in UV-C and UV-B range are close to zero. Wave length (nm) All UV-lamps are subject to thorough quality control and can be supplied with an analysis certificate about the spectral irradiation intensity upon request.

Over the past few years the powerful compact UV LED lamps have improved remarkably especially for magnetic particle testing and penetrant testing by use of fluorescent materials. The most significant advantages of these lamps are the low power consumption (thus enables battery or accumulator feeding), a very long lifetime, no warm-up time and above all the defined UV wavelength in the UV-A range () with the emission half-width of. This wavelength ensures maximum contrast between the crack indication and its background. Through the quasi-monochromatic emission spectrum of the UV light-emitting diodes there is no irradiation part, which is adjected to visible light ( 400 nm) or lies within. Irradiation in the visible range results in undesirable brightening and reflection, especially while testing metallic shiny, curved objects. Such reflections are not only perceived by an inspector as artifacts, they also reduce the contrast and therefore affect the defect recognition. 2000 Radiation intensity µw/cm² Wave length (nm) 1500 1000 500 0 5 10 15 20 X cm 25 30 35 40 45 5 30 35 25 20 15 10 Y cm Spectral radiation intensity UV intensity distribution ZERO 100/1 IP65 stationary UV LED lamp Art.No. 144.200.063 ZERO 100/1 is a small-sized stationary UV LED lamp of the IP65 protection class.
