T1 - PTB detector calibration capabilities for optical radiometry T2 - Sensor 2001 Proceedings N2 - In the first part of this paper we give a brief survey of the approaches taken to achieve these rather challenging goals. Then we will focus on some aspects of transfer detector standards that have to be taken into account if the highest possible accuracy is to be reached. The final section of the paper deals with a new and very promising method for the dissemination of the spectral responsivity of semiconductor photodiodes.
