Abstract

The connection between illuminance and luminance measurements is considered to create a traceability link among an highly accurate illuminance meter, considered as an internal standard of the Photometric Laboratory of the University of Padova, and other illuminance meters or photometric heads and luminance meters. Examples are presented in the paper. The application of a detector-based method allows a significant reduction of the uncertainty in the internal calibration of the photometric instruments, granting the continuity of the Laboratory operation, contemporarily.
