NIR-SPD-900-1700-FR Near infrared single photon detector is a light detector module based on InGaAs/InP process. Working in Free runnning mode, it can detect and count light pulses of single photon level under low light conditions. It has the characteristics of high detection efficiency, low dark count rate and low post-pulse probability. At the same time, the module is compact in structure and stable in performance.

The detector employs active quenching and active reset technologies, and is integrated with a built-in Time-to-Digital Converter (TDC) function. It can statistically collect and output the time information of incoming single photons in real time, eliminating the need for customers to build an external TDC system.

NIR-SPD-900-1700 Near infrared single photon detector is a light detector module based on InGaAs/InP process. Working in pulse gated mode, it can detect and count light pulses of single photon level under low light conditions. It has the characteristics of high detection efficiency, low dark count rate and low post-pulse probability. At the same time, the module is compact in structure and stable in performance.

It can be used as the upper computer data communication through the USB serial port, and can also directly detect the output pulse signal, which can be used to access the system or counter. The maximum external trigger frequency can be supported by 100MHz.


Features

  • Compact structure and stable performance
  • Maximum 100MHz gated repetition frequency
  • Gated synchronization input interface
  • Extremely low dark count rate and afterpulse probability
  • Up to 4 devices can work in cascade

Application 

  • Quantum optics, quantum secure communication
  • Quantum imaging, quantum entanglement
  • Photon number calibration of pulse light source
  • Laser ranging, lidar (LIDAR)
  • Fluorescence spectroscopy, time-resolved single molecule measurements
