The detector UV-3711-308 is designed for irradiance measurement of 308nm Eximer lasers used in monochromatic UV-B therapy for treatment of psoriasis and vililigo. The flat spectral responsivity around the 308 nm reduces the measurement uncertainty in case of wavelength shift of the Eximer laser.

Traceable calibration 

Calibration of the detector UV-B (W/m²) responsivity at 308nm 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.
