Figure 11: Signal intensity prole
Within the framework of less than 1 electron falling on a pixel in a single exposure, the EMCCD can be used in Photon
Counting Mode. In this mode, a threshold is set above the ordinary amplier readout and all events are counted as
single photons. In this mode, with a suitably high gain, a high percentage (>90%) of the incident photons can be counted
without being affected by the Noise Factor effect.
