The MPPC (Multi-Pixel Photon Counter) is a new type of photon-counting device made up of multiple APD (avalanche photodiode) pixels operated in Geiger mode. The sum of the output from each APD pixel forms the MPPC output. This allows the counting of single photons or the detection of pulses of multiple photons. The MPPC is used in diverse applications including fluorescence analysis, fluorescence lifetime measurement, flow cytometry, single molecule detection, neutrino detection, and PET (positron emission tomography).
The MPPC is essentially an opto-semiconductor device with excellent photon-counting capability and which also possesses great advantages. Features of the MPPC include the following:
Excellent photon detection efficiency High gain: 105 to 106 Room temperature operation Low bias (below 100 V) operation Insensitive to magnetic fields Excellent time resolution Compact and rugged
