Title: Comparison of laser-based and monochromator-based thermodynamic temperature measurements

In this work, we describe comparisons between a laser-based and a monochromator-based radiance responsivity calibration of a radiation thermometer. The spectral selection of the radiation thermometer is performed using a spectrally broad photopic-response filter which was selected to minimize effects of convolution differences due to the spectral width of the laser-and the monochromator-based sources. The photopic-response filter is physically thick, which should also reduce possible interference fringes which can be problematic in the laser-based calibrations. We 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.
