Abstract

Based on Fourier infrared spectrometer, the mid-infrared normal spectral emissivity measurement device with high accuracy was developed in Spectrophotometry Laboratory, National Institute of Metrology, China. It was composed of Fourier infrared spectrometer, black body, heater and the auxiliary optical components. It can work at 100 to 450°C with heating function and can work at up to 1100°C only for self-heating materials or systems. The measurement wavelength range covers the whole middle infrared light 2.5-25um, and the measurement uncertainty is better than 2%(k=2) at any measurement temperature point for self-heating materials or systems.
