These include bioluminescence, fluorescence spectroscopy, and astronomy. Thus, avalanche photodiodes generates more number of charge carriers than PN and PIN photodiodes. Avalanche detectors utilize internal multiplication through impact ionization to achieve very high sensitivity (>40A/W peak at Gain=100). This allows each photo-generated carrier to be multiplied by avalanche breakdown , resulting in internal gain within the photodiode, which increases the effective responsivity of the device. The light collected by WLS fibers (0.84 and 1 mm diameter) embedded in the scintillator has been transmitted to the 0.5 mm 2 active surface of APD by clear optical fibers and optical connectors. In Geiger mode, an APD is biased several volts above breakdown voltage for operation at very high gain (typically 105 to 107). Avalanche Photodiode. View Products & Descriptions.
