Abstract
New primary standard apparatus of spectral radiance was setup at National Institute of Metrology (NIM) based on high temperature blackbody BB3500M in 2011. Wavelength range was extended to 220 nm - 2550 nm. The measurement uncertainty of temperature was 0.64 K (k=1) at 2980K traceable to the Ag, Cu, Co-C, Pt-C and Re-C fixed point blackbodies, and checked by a WC-C fixed point blackbody. Good consistency was obtained by using two different imaging optics with varied solid angle and different object distances, the relative deviation is less than ±0.4 % at all wavelengths. A set of characteristic experiments were designed and analyzed in this paper, such as alignment error and the influence of the different shape and size of the water-cooled precise aperture, the polarization effects etc. NIM participated spectral radiance international comparison APMP.PR-S6 by using this new developed apparatus in 2014 with measurement uncertainty (k=1) 0.95% at 250nm, 0.50% at 400nm, 0.41% at 800nm, and 0.80% at 2500nm respectively.
