A radiation thermometer centered at nm is calibrated using the detector-based temperature of a gold freezing temperature blackbody. The temperature scale is maintained using a vacuum strip lamp, and the temperature of a mm diameter variable-temperature blackbody (VTBB) is assigned by comparisons using the radiation thermometer.

The facility for automated spectroradiometric calibrations (FASCAL) is the primary facility for calibration of spectral irradiance and spectral radiance at NIST and has been in continuous use.

Brightness temperature or radiance temperature is the temperature of a black body in thermal equilibrium with its surroundings, in order to duplicate the observed intensity of a grey body object at a frequency.

This concept is used in radio astronomy, planetary science and materials science. The brightness temperature of a surface is typically determined by an optical measurement, for. radiance to Modtran-derived water vapor absorptions. 0 20 40 60 80 wavelength (nm) transmission sphere calculated radiance sphere reported radiance atmospheric transmission (modtran) Figure 8: sphere.
