A mercury-vapour lamp has the spectral output shown above.
For applications where a different wavelength of UV is required, the spectral output of a standard lamp can be shifted to different wavelengths by utilising energy transfer from the mercury atoms within the arc to another material added during manufacture. The spectra of some spectrally-enhanced lamps are shown below
Whilst Primarc manufacture equivalent lamps to makes such as Hanovia, Heraeus, Superior Quartz, IST, Eltosch, Hoenle, Grafix, GEW, etc, it is important to identify the specific lamp for your UV drying system. Please complete the lamp identification sheet so that an equivalent lamp can be identified.
