Report on the characterisation and calibration of transfer standard spectroradiometers from at least 5 end user applications (to enable the detector-based traceability of spectral irradiance measurements as an alternative to the incandescent lamps-ba

Radiometric calibrations of array spectroradiometer instruments took place at NMI and DI facilities using well-established characterization methods, allowing direct traceability to the SI system. Each consortium partner involved in this activity has produced a report of the characterizations in their laboratories. This deliverable reports the results of these characterizations and the methodology to follow for a complete calibration of array spectroradiometers to potentially be qualified as irradiance transfer standards. In addition to the characterization procedures and results, this report provides the analyses of retrieved instrumental parameters to be considered in the measurement process.
