Abstract
At the Physikalisch-Technische Bundesanstalt (PTB), the national metrology institute of Germany, the calibration facility for thermal imager, infrared calibrators, and radiation thermometers has been up-dated to improve the calibration service. An additional cesium-heatpipe blackbody was installed to close the temperature gap from 270 °C to 500 °C and a new sodium-heatpipe blackbody was taken into operation. In addition, the precision of the positioning of the devices under test was improved and the new blackbodies were characterized and tested. The calibration facility now marks the state-of-the-art in terms of achievable uncertainties and automatization.
