متن کاملOptical Filter Transmittance Measurements by a Double-Beam Spectrophotometer for Calibration of Fluorescence Detector AUGER Filter Samples
An experimental setup and procedure for accurate transmittance measurements of candidate filters for the Auger Fluorescence Detector is presented. For this check, we used the Hitachi U-2000 double-beam spectrophotometer (Sph) of the Chemical Department of the University of Athens (UoA). After the calibration of the Sph, we are able to observe transmittance deviations over the area of the filter...
