Abstract

Narrow bandpass UV radiometers are used in a variety of high-temperature measurement applications. These instruments are traditionally calibrated using spectrally flat deuterium lamps. Accurate calibration of these instruments requires detailed knowledge of the filter transmission function and the spectral sensitivity of the photodetector, as well as assumptions about the spectral intensity distribution of the source itself. Significant systematic errors, in the form of an apparent wavelength shift in the system response curve may be introduced when interpreting data obtained from spectrally nonuniform sources (e.g. gray-or blackbody sources). Theoretical calculations, using transmission curves from commercially available narrow bandpass filters, show that the apparent shift in the system spectral response is a function of temperature for a blackbody source. A brief comparison between the theoretical analysis and experimental data is presented.
