The VioSpor^® system is subject to constant quality control. System validation is carried out using in-vivo comparative measurements.

The wavelength-specific calibration of VioSpor^® is carried out using measurements on the Okasaki spectrograph in Japan (lamp performance based on the US radiation strength norm of the National Institute of Standards (NIST)).

Additionally VioSpor^®was validated during several instrument intercomparisons performed under field conditions. VioSpor^®data were compared with the MED values calculated from spectroradiometer data.
