The ID Qube NIR Free-Running brings a major breakthrough for single-photon detection in free-running operation at telecom wavelengths.It provides a cost-effective solution for applications in which asynchronous photon detection is essential, such as photon correlation or time of flight measurements. Moreover, it is especially suited for applications such as LiDAR, where compactness is a key requirement.

The detector offers a gate input port connector, designed to avoid saturation or undesired detections. The cooled InGaAs/InP avalanche photodiode and associated electronics have been designed to achieve especially low dark count and afterpulsing rates.

The ID Qube NIR Free-running is available in free-space or fibre-coupled (MMF 62.5 μm FC/PC) versions.
