Single Photon Detector Systems

VSI Single Photon Detector Module Series

The family of VSI series Single Photon Counting (SPC) and Time-of-Arrival (TOA) Instruments are ideal for various nearinfrared (NIR) applications, from single photon counting, to LADAR and LIDAR ranging, to time correlated single photon counting (TCSPC).

Performance Features:

  • Low-noise InGaAs detection
  • Up to 50 picosecond timing resolution
  • 0.9 μm - 1.65 μm response
  • Low dark count rates and low excess noise combine for superior sensitivity
  • 1, 2, 4 or 8 channel modules available
  • APD active quenching for each channel
  • Gigabit Ethernet interface
