News

Im Rahmen des im Metrologischen Forschungsprogramms EMRP geförderten Projekt NEWSTAR wurde experimentell die Berechenbarkeit eines berechenbaren quanteneffizienten Detektors bzgl. seines polarisations-, winkel- und bandbreitenabhängigen Verhaltens überprüft und bestätigt. Die Empfindlichkeit eines Photometers wurde schließlich gegen diesen Detektor kalibriert und das Ergebnis mit dem Wert verglichen, der sich aus der Kalibrierung entsprechend der aktuellen Rückführungskette ergibt, wobei sich eine Übereinstimmung im Rahmen der Messunsicherheit ergab.
