As a typical application, a halide lamp of 40 W
was calibrated in terms of distribution temperature.
The distribution temperature values obtained for
different spectral sub-intervals are tabulated below :
Nr. Wavelength range T i, i+1
1 400 nm…500 nm 2920 K
2 440 nm…550 nm 2929 K
3 500 nm…600 nm 2934 K
4 550 nm…670 nm 2938 K
5 600 nm…750 nm 2955 K
6 670 nm…800 nm 2983 K

5 Conclusions and further steps
A multifiltered radiometer was developped and
characterised at NIM-Romania. It allows both
temperature distribution and spectral irradiance
measurements. To validate the method employed and
the estimated mesurement uncertainty a bilateral
comparison with LNE-INM, France is in progress.
