Abstract: A vacuum emissometer utilizing a CO$-2$/ laser for high temperature sample heating has been designed and built for use with a Fourier Transform spectrometer. A two-color pyrometer technique is used to calculate sample temperatures. Oxides such as sapphire, spinel, yttria, ALON and fused silica are experimentally characterized from 600 to 2000 K and from 500 to 5000 cm$+$MIN@1$/. A glowing yttria sample has also been characterized over the spectral range of 8500 to 13500 cm$+$MIN@1$/. Good agreement with a quantum mechanical multiphoton model for the complex index of refraction, also developed at APL, is obtained.!17
