Abstract
The paper contains the state-of-the-art of the precision radiometry principles based on using high temperature blackbody sources, as well as the characteristics of blackbodies (BB), developed at the All-Russian Research Institute for Optical and Physical Measurements (VNIIOFI). A novel Medium Background Facility (MBF) intended for calibrating both IR sources and sensors has been developed at VNIIOFI. The MBF used for the calibration under vacuum conditions (10-3 Pa) and medium background temperatures includes a Ga Fixed-Point Blackbody (29.76 degree(s)C), Variable Temperature Blackbody (-60 degree(s)C ~ +80 degree(s)C) and Filter Radiometer. Both blackbody spectral radiometric calibration and effective emissivity measurement are performed in the spectral range from 2.5 micrometers to 14 micrometers for a blackbody temperature from -60 degree(s)C up to +80 degree(s)C. A brief description of the operating principles and specifications of the MBF is presented.
