The ID Qube NIR Free-Running brings a major breakthrough for single-photon detection in free-running mode 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 strongly required.
The detector offers a gate input port connector dedicated to avoid saturation or undesired detections. The cooled InGaAs/InP avalanche photodiode and associated electronics have been specially designed to achieve low dark count and afterpulsing rates in free-running mode.
The device is available in free-space, SMF or MMF (62.5 ?m) fibre- coupled version.
