Optimal signal-to-noise ratio

PILATUS3 Hybrid Photon Counting detectors are inherently free of dark current and readout noise. The absence of any detector noise guarantees data with an excellent signal-to-noise ratio (Fig. 1).

Fig. 1: Comparison of data quality of flatpanel and PILATUS3 X CdTe detector. The photon-counting CdTe detector shows significantly less noise resulting in improved visibility of weak diffraction rings. Acknowledgment: These powder diffraction patterns were measured by Marco Di Michiel at the High-Energy Scattering Beamline ID15A of the European Synchrotron Radiation Facility (ESRF) using the same settings (photon energy of 46.3 keV and 0.1 s exposure time) on both detectors.
