HIGH EMISSIVITY VTBB FURNACENo.CX-141-01AE

IR-R20Realize high effective emissivity in a wide wavelength range

High Emissivity VTBB (Variable Temperature Blackbody)
Furnace is a blackbody source for calibration of radiation
thermometers, developed in collaboration withthe National Metrology Institute of Japan (NMIJ), AIST.
Vertically aligned CNT (Carbon Nanotube) is grown on thesurface of the cavity bottom. As a result, it realizes higheffective emissivity in a wide wavelength range.
Thus this unit drastically reduces the uncertainty incalibration of radiation thermometers, even when comparing
thermometers with different measuring wavelengths.
