The Comparison of different types of Spectroradiometers in terms of Uncertainty of measurement
Original language description
This article describes and compares different types of spectroradiometers in terms of uncertainty of measurement of spectral power distribution. Measurement of spectral power distribution is important for evaluation of main photometric quantities. In order to compare different types of spectroradiometers, it is used scanning spectroradiometer with single detector and double monochromator as reference. Although uncertainty of the measurement of spectroradiometer is known, there are complications with measuring narrow spectral peaks. With small bandwidth it is possible to measure narrow peaks correctly. However with wider bandwidth the measured peaks are more widespread. Thus compact array spectroradiometers can be used for measuring light sources with wide spectrum without peaks. However for measuring discharge lamps and LED with narrow spectrum with acceptable uncertainty of measurement it is necessary to use single or double slit monochromator. Next task is focused on testing spectral accuracy of different spectroradiometers. Spectral shift can influence calculated photometric quantities.
