Infrared InGaAs/InP SPAD Detector

ID-230
  • TCPSC in the Infrared Spectral Range

  • Detection from 900 nm to 1700 nm
  • Single-Photon Sensitivity
  • Quantum Efficiency 25 %

Please see 80 ps FHWM Instrument Response with ID230 InGaAs SPAD and SPC-150 TCSPC Module

The ID Quantique ID230 InGaAs SPAD delivers an instrument response width of 80 ps FWHM with the bh SPC-150N TCSPC module. This is the fastest TCSPC response reported for InGaAs SPADs so far. Compared to its predecessor the new InGaAs SPAD also has a much lower dark count rate. The detector we tested had less than 300 dark counts when operated with a dead time of 40 μs.
