Abstract
The Physikalisch-Technische Bundesanstalt (PTB) expanded its capabilities of absolute calibration of the spectral responsivity in the mid-infrared (MIR) by equipping a cryogenic electrical substitution radi-ometer facility with MIR laser radiation sources to enable absolute measurement of radiant power traceable to the International System of Units (SI). Furthermore, the PTB is installing a new MIR de-tector comparator facility to disseminate the spectral responsivity from the absolutely calibrated trans-fer standards to other detectors.
