The first setup consists of several heat-pipe blackbodies in conjunction with platinum resistance thermometers, calibrated according to the International Temperature Scale of 1990 (ITS-90) and is applied for calibrations in the temperature range from-60 C to 961.78 C. In the temperature range from 962 C to 3000 C the calibration is based on high temperature blackbodies. The temperature of these blackbodies is determined in two independent ways: traceable to the ITS-90 gold fixed point or via absolutely calibrated filter radiometers (FR) traceable to the detector primary standard, the cryogenic radiometer. Taking advantage from the high accuracy of the FR calibration, these FRs have also been successfully used for the investigation of the thermodynamic accuracy of the ITS-90 in the range from 419 C to 962 C. For non-contact temperature measurements, the emissivity of the observed object is one of the most important parameters. Therefore, PTB has set up instrumentations for measuring the directional spectral and total emissivity of samples in air from 80 C up to 400 C over a spectral range from 4 µm to 40 µm and under vacuum from 0 C to 600 C and in the spectral range from 1 µm to 1000 µm.}, language = {en} } @inproceedings{HartmannKrenekAnhaltetal., author = {Hartmann, J{\"u}rgen and Krenek, S. and Anhalt, Klaus and Lindemann, A. and Monte, C. and Hollandt, J{\"o}rg}, title = {A study on the feasibility of measuring the emissivity with the laser-flash method}, address = {Boulder (USA)}, language = {en} } @inproceedings{HartmannMonteAnhaltetal., author = {Hartmann, J{\"u}rgen and Monte, C. and Anhalt, Klaus and Gutschwager, B. and Taubert, Dieter Richard and Hollandt, J{\"o}rg}, title = {Calibration of Radiation Thermometers and Measurement of Spectral Emissivity Traceable non-contact temperature measurements in industrial and scientific applications}, series = {Proceedings Sensoren und Messsysteme 2008}, booktitle = {Proceedings Sensoren und Messsysteme 2008}, pages = {249 -- 261}, language = {en} } @inproceedings{HartmannAnhaltGutschwageretal., author = {Hartmann, J{\"u}rgen and Anhalt, Klaus and Gutschwager, B. and Monte, C. and Sperfeld, P. and Taubert, Dieter Richard and Hollandt, J{\"o}rg}, title = {The PriTeRa facility of PTB for spectral radiance and irradiance calibrations and radiation thermometry in the range from -170 °C up to 3200 °C and from 200 nm up to 50 µm}, series = {Proceedings of NEWRAD}, booktitle = {Proceedings of NEWRAD}, pages = {231 -- 232}, language = {en} } @inproceedings{HartmannTaubertMonteetal., author = {Hartmann, J{\"u}rgen and Taubert, Dieter Richard and Monte, C. and Gutschwager, B. and Hollandt, J{\"o}rg}, title = {Traceable Calibration of Radiation Sources from the Visible to the Far Infrared for Space Borne Applications at PTB}, address = {Berlin}, language = {en} } @inproceedings{HartmannTaubertMonteetal., author = {Hartmann, J{\"u}rgen and Taubert, Dieter Richard and Monte, C. and Gutschwager, B. and Hollandt, J{\"o}rg}, title = {Traceable calibration of radiation sources from the visible to the far infrared for space borne applications at PTB}, series = {Proceedings of SPIE Volume 7474, Sensors, Systems, and Next-Generation Satellites XIII}, booktitle = {Proceedings of SPIE Volume 7474, Sensors, Systems, and Next-Generation Satellites XIII}, abstract = {The Physikalisch-Technische Bundesanstalt (PTB) has developed dedicated instrumentations and methods for the traceable calibration of space borne instruments in terms of the three fundamental radiometric units, i.e. spectral radiance (radiation temperature), spectral radiant intensity and spectral photon flux.
