Description
Summary:To improve the realization of luminous intensity a new photometric detector has been developed at Physikalisch-Technische Bundesantalt (PTB). This detector will be used to realise a radiometric traceability chain for luminous intensity with a lowered measurement uncertainty. To allow a short and direct calibration hierarchy, a trap detector was chosen that will be used with several modular attachments for each calibration step. Achieving a reduced measurement uncertainty requires careful design and characterization of each module used. The new calibration strategy and the detector with its several setups are described here.
