Silicon Photomultipliers (SiPMs) are silicon-based solid state low level light sensors. They are basically an array of silicon avalanche photo diodes (APDs), each operated in Geiger-mode. This results in the SiPM’s advantages of high gain, low temperature dependency, easy operation and enhanced next generation sensor performance.

KETEK Silicon Photomultipliers (SiPMs) are novel solid-state silicon detectors with single photon counting capability. SiPMs excel in many applications and feature high gain with very low temperature drift, extremely good timing performance at a low operating voltage. They are also insensitive to magnetic fields and stand out with their mechanical robustness. KETEK provides cost-effective solutions from high volume applications to customized detector solutions.

SiPM Features:

  • Single photon resolution
  • High photon detection efficiency
  • High gain and high signal to noise ratio
  • Very compact devices
  • Low bias voltage
  • Insensitive to magnetic fields

 

  • Superior time resolution
  • Counting and CW measurements
  • Simple calibration and monitoring
  • Not damaged by daylight
  • Low costs

SiPMs combine the benefits of vacuum PMTs (high photon detection efficiency, gain and signal-to-noise) with the benefits of APDs (robustness, miniaturized design, low operation voltage, cost-effective and magnetic insensitivity) to an outstanding low level light sensor with an exceptional performance at low cost. KETEK’s fabless foundry business is offering cost-effective in-time production with scalability to nearly any imaginable customer demand.
