id120 single-photon detector

The id120 series consists of compact and affordable single-photon detector modules based on a reliable silicon avalanche photodiode, sensitive in the visible spectral range.

The two new detectors of the id120 series have high efficiency values (up to 80 per cent) in the red region of the visible spectrum and a 500µm large active area. These new detectors come as:

  • free-space module, passive quenching, maximal efficiency value up to 60 per cent around 650nm

  • free-space module, passive quenching, maximal efficiency value up to 80 per cent around 800nm.

Those two detection modules are highly versatile thanks to an USB connection and a Labview interface, allowing the user to change the bias voltage, the deadtime and the temperature of the diode. Thus the user is able to control quantum efficiency, dark count rate, and after-pulsing rate. The modules are equipped with a dual universal output signal port which can be set through the software interface. The modules are compatible with C-mount, SM1 and cage technologies. This allows an easy coupling of the light beam onto the active area of the detectors.
