Multi-Pixel Photon Counter
2021-09-07
●Photosensors with excellent photon-counting capability
●The MPPC (multi-pixel photon counter) is a type of photosensor called SiPM (silicon photomultiplier). It is a photon-counting device using multiple APD (avalanche photodiode) pixels operating in Geiger mode. Although essentially an opto-semiconductor device, it has excellent light receiving capability and can be used in various applications for detecting extremely weak light at the photon counting level.
●The MPPC operates on low voltage and features high gain, high photon detection efficiency, high-speed response, excellent time resolution, and wide spectral response range. It achieves the high-level performance required in photon counting. It is also immune to magnetic fields, highly resistant to mechanical shocks and the like, and will not suffer from “burn-in” by incident light saturation, which are advantages unique to solid-state devices.
●Features of MPPC:
■When an MPPC detects photons, the output may contain false signals, namely afterpulse and crosstalk, that are separate from the output pulses of the incident photons. Hamamatsu MPPC maintains high photon detection efficiency while featuring low afterpulse, low crosstalk, and low dark count.
■Low crosstalk
■Low afterpulses
■Low dark count, high gain, high photon detection efficiency
