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 efciency while featuring low
afterpulse, low crosstalk, and low dark count.
FEATURE 1
Low crosstalk
The pixel that detects photons may affect other pixels, making them produce pulses separate from output pulses. This
phenomenon is called crosstalk. MPPC employs a structure that suppresses the occurrence of crosstalk.
R
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 elds, 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.
