High Emissivity VTBB Furnace IR-R20

High Emissivity VTBB (Variable Temperature Blackbody) Furnace is developed in collaboration with the National Metrology Institute of Japan (NMIJ) of AIST. IR-R20 is VTBB (Variable Temperature Blackbody) Furnace for comparison calibration of radiation thermometers.

  • Realizes high effective emissivity (0.999±0.001) in the wide wavelength range
  • Reduces uncertainty in calibration of radiation thermometers in the wavelength range from 1.55μm to 14μm drastically
  • Compact and light weight
