Abstract
In this work, we describe the comparisons between the laser-based and monochromator-based radiance responsivity calibrations of a radiation thermometer. The spectral selection of the radiation thermometer is performed using a photopic-response filter which is spectrally broad in order to minimize the effects of convolution differences due to the spectral width of the laser- and the monochromator-based sources. The thick photopic-response filter also reduces the possible interference fringes which can be problematic in the laser-based calibrations. We will compare the radiance responsivities obtained using the two approaches and also compare the blackbody temperatures determined using the detector/monochromator based and the gold-point based calibration methods.Proceedings Title
