The Practical Correction of Wavelength Uncertainty of Array Spectroradiometers

This article has task to inform a reader about wavelength uncertainty of array spectroradiometers and propose corrections that can be performed on measured spectral data or moreover on photometric quantities that are already calculated from measured spectrum. Therefore, a several array spectroradiometers are tested on spectral accuracy and corrections coefficients are calculated for illuminance measurement for typical spectrums of fluorescent and LED light sources.
