High sensitivity, low noise MPPC for visible and near infrared region

MPPC, also called SiPM (silicon photomultipliers), is a new type of photon counting device that consists of multiple Geiger mode APD (avalanche photodiode) pixels. It is an opto-semiconductor with outstanding photon counting capability and low operating voltage and is immune to the effects of magnetic fields.
The S14422 series is an MPPC for the visible to near infrared region. It provides higher photon detection efficiency than the previous product (S13362 series) in the visible to near infrared region. In addition, the built-in TE-cooler function provides low crosstalk and low afterpulses as well as reduces the dark count to 1/10 that of the non-cooled type.


- Low dark count: 1/10 that of the non-cooled type (-10 ℃)
- High photon detection efficiency: 40% (λ=600 nm, Vop=VBR + 5)
- Low crosstalk, low afterpulses
- Low voltage (VBR=40.5 V typ.) operation (-10 ℃)
- High gain: 105 to 106
- Operates with simple readout circuits
- MPPC module also available (sold separately)
