| Zusammenfassung | The uncertainty for photometric responsivity calibrated with the tunable lasers in photometry setup (TULIP) at Physikalisch-Technische Bundesanstalt (PTB) is presented. The measurement and the uncertainty calculation presented were done in preparation for the upcoming new traceability chain for luminous intensity at PTB. Regarding the new traceability a comprehensive uncertainty calculation is needed to take into account all steps of the traceability chain. The components of the measurement model are described and the correction factor for bandwidth and the inclusion of correlations are evaluated in detail. Assumptions that can help accessing unknown spectral correlations are described and their effect on the measurement uncertainty of photometric responsivity is calculated. |
