With known radiometric data of the components of the projection perimeter and its accessories it is possible to perform spectral sensitivity measurements which are essential for the performance of quantitative colour perimetry. The authors describe modifications made with the Goldmann perimeter for the performance of such measurements. The calibration data of the perimeter and accessories are given. A good fit between the CIE scotopic spectral sensitivity curve (V'λ) and our experimental results for a dark adapted eye serves as a control of the calibration.
