WebPhoton Correlation Spectroscopy Quantum Optics LIDAR Features Single Photon Detection or Counting Modules Visible and NIR Wavelength Responsivity Low Max Dark Count … WebCount Rate Linearity: At high rates of photon incidence the SNR will decrease due to saturation. Photon counting circuits have an inherent dead time which limits the minimum arrival time between successive photon detections. Thus at high count rates the detector experiences pulse pile-up effects which results in missed counts.
