The calibration of integrating sphere with spectroradiometer with traceability to goniophotometer

This article has task to inform a reader calibration procedure of an integrating sphere with spectroradiometer as detector with traceability to goniophotometer and double monochromator. In the first part there is a description of each step of calibration including preparations for necessary measurement and equipment. In the second part there is a description of practical calibration in light laboratory at Brno University of Technology with results and recommendations. Last part concludes results of calibration along with uncertainty budget evaluation.
