The XD-9502 detector includes a broadband radiometric UV-A (315 nm - 400 nm) detector and illuminance detector with a V(λ) matching
Cosine Corrected Field of View
Both sensors of the XD-9502-4 detector are cosine corrected.
Traceable calibration
Calibration of the detector 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.
