SPECTRAL AND TOTAL EMISSIVITY APPARATUS AND MEASUREMENTS OF OPAQUE SOLIDS

Abstract

Three methods of measuring the normal spectral, total normal and total hemispherical emissivity of opaque solid materials are described. Spectral emissivity measurements are performed at approximately ambient temperature and encompass the wavelength interval .4 to 25 microns. Total hemispherical emissivity measurements cover the temperature range 0 C to 600 C. Results of the emissivity measurements, of various materials, as performed with each of the systems, are presented. (Author)
