T1 - Irradiance measurements of Re-C, TiC-C and ZrC-C fixed point blackbodies BT - Newrad 2005 N2 - Specially designed Re-C, TiC-C and ZrC-C fixed-point cells for irradiance measurements have been produced by VNIIOFI. In several investigations at VNIIOFI and PTB the usability of the design for irradiance measurements has been demonstrated. Current developments of furnace uniformity demonstrate further improvements to the systems.
