Abstract. A new spectral method for measuring the emissivity of solids at high temperatures is considered. The method is based on determination of wavelength dependence of the studied body spectral brightness in a narrow spectral range. Theoretical substantiation and results of experimental verification of the method are presented.
Keywords: spectral emissivity, gray body, measurement, high temperature, energetic radiance, wavelength
