Abstract: A new facility for the measurement of the normal spectral emissivity of solid materials for high-temperature applications in the thermal steady state was developed at the Bundeswehr University of Munich. The measurements are performed under atmospheric conditions. The facility covers the temperature range between $$500\,^{\circ }\hbox {C}$$ 500 ∘ C and $$1350\,^{\circ }\hbox {C}$$ 1350 ∘ C and wavelengths between $$0.6\,\upmu \hbox {m}$$ 0.6 μ m and $$15\,\upmu \hbox {m}$$ 15 μ m . The principle of operation involves the spectral comparison of a test sample with a reference blackbody and the sample surface temperature determination with a numerical spectral ratio calculation. The optical characteristics of the blackbody and the sample surface temperature determination are discussed in detail. Furthermore, measurement results of the quasi-reference material silicon-carbide under steady-state conditions are presented to validate the measurement method. [ABSTRACT FROM AUTHOR]
