SensL Technologies are the world's leading commercial supplier of Silicon Photomultipliers (SiPMs) which are rapidly replacing conventional vacuum PMTs and silicon avalanche photodiodes (APDs) due to a combination of exciting features:-


  • Low operating voltage - less than 30V for gain of 6 million
  • Tightly controlled breakdown/operating voltage uniformity - ±250mV
  • Low temperature dependence of breakdown voltage - 21.5mV/°C
  • Immunity to magnetic fields
  • MRI compatible packaging - J-series
  • Small size whilst mechanically and optically robust with no damage from high-light levels
  • Multi-channel arrays can be made with fine pitch resolutions not possible in vacuum PMTs


SensL's product range comprises three SiPM families:-



High volume, low noise
