Results of a NIST/VNIIOFI comparison of spectral-radiance measurements

A comparison of the spectral-radiance scales of the National Institute of Standards and Technology (NIST) and the All-Russian Research Institute for Optophysical Measurements (VNIIOFI) was carried out in 1989 and 1990. The spectral range of the comparison was between 240 nm and 2400 nm. The transfer...

Summary:A comparison of the spectral-radiance scales of the National Institute of Standards and Technology (NIST) and the All-Russian Research Institute for Optophysical Measurements (VNIIOFI) was carried out in 1989 and 1990. The spectral range of the comparison was between 240 nm and 2400 nm. The transfer standards were argon-filled tungsten ribbon filament lamps. The NIST/VNIIOFI agreement was 0,5 % to 1 % in the 240 nm to 800 nm range, and better than 0,5% between 900 nm and 2400 nm. On average, the spectral radiances measured at the VNIIOFI were slightly higher than the NIST values.
