Ultraviolet radiation is used in the treatment of certain skin diseases like Psoriasis and for photobiological studies like SPF testing. Measuring the source irradiance or energy is required for accurate dosimetry and safety purposes. Typical wavelength ranges of interest are UV-A: 320nm - 400 nm, UV-B: 280 nm - 320 nm and UV-B: 311 nm. The two cell XD-9501 detector includes filtered detectors for both the UV-A and UV-B spectral ranges and a cosine corrected field of view.

Traceable calibration

Calibration of the detector UV-A and UV-B (W/m²) responsivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik calibration of absolute detector responsivity as well as detector individual measured relative spectral responsivity data is included.
