Abstract：With the new spectral irradiance measurement facility based on blackbody BB3500M of NIM (National Institute of Metrology), a bilateral spectral irradiance comparison was carried out between NIM and VNIIOFI (All Russian Research Institute for Optical and Physical Measurements) in the spectral wavelength from 250 nm to 2500 nm in the period from December 2014 to January 2015. The temperature measurement of the high temperature blackbodies were traced to the Pt-C and Re-C fixed point blackbodies and checked against the WC-C fixed-point blackbody for the two institutes respectively. The consistency of the temperature at 3021K is better than 70mK. The comparison result shows that the average relative deviation of spectral irradiance at the 44 wavelengths is 0.45%. The consistency is better than 0.9% except the maximum deviation 1.1% at the wavelength of 2000nm. The spectral irradiance units measured by NIM and VNIIOFI in this comparison are in agreement within the combined standard uncertainties of the laboratories over the wavelength range compared.
