Single Photon Avalanche Diode (SPAD) is the new generation of Geiger-Muller counter device developed in semiconductor technology [1-3]. Physical dead time model and noise production process has been analyzed and their corrections have been performed. We have been able to extract the real amount of incident photon rate up to 10(7)cps using a device with 0.97 mu s total deadtime. We also developed the equation of the noise count rate vs incoming photon rate, supported by Montecarlo simulation and experimental data. We marked the difference between dark rate and noise count rate, and introduced the noise rate inside the hybrid deadtime equation used for SPAD device.
