SiPM Products

Single photon detection with Silicon Photomultiplier (SiPM) products

Silicon Photomultipliers are arrays of avalanche photodiodes operated in Geiger mode (SPADs), designed for the detection of extremely weak light, down to a single photon. Depending on the light source and application, several hundred to thousands of SPADs are connected in parallel to form an SiPM. Each SPAD includes an integrated series resistor, which quenches the avalanche and resets the diode for the next incoming photon. The SiPM signal output is an electrical current proportional to the number of photons hitting the sensor. The main signal features are very high gain (>1 x 10⁶), very fast response and short recovery time.

Application fields are those requiring weak light detection and/or very good timing information. Typical examples are scintillator-based detectors and time-of-flight systems. Examples are Medical, IVDx, Flow Cytometry, Safety & Security, Radiation Spectroscopy, and HEP experiments.

Key benefits:

  • High PDE
  • High dynamic range
  • Low cross-talk
  • Low dark count rate
  • Short recovery time

Broadcom AFBR-S4N44P164M

Silicon Photomultiplier (SiPM) array used for ultra-sensitive precision measurements of single photons.

The Broadcom® AFBR-S4N44P164M is a 4×4 silicon photo multiplier (SiPM) array used for ultra-sensitive precision measurements of single photons. This combines best-in-class photodetection efficiency (PDE) with decreased dark count rate and reduced crosstalk. The pitch of SiPMs is 4 mm in both directions. The encapsulation is realized by an epoxy clear mold compound, which is highly transparent down to UV wavelengths.
