ID Qube NIR Gated

The ID Qube NIR Gated is a fast-gated single photon detector optimized for telecom wavelengths.

The ID Qube delivers precise and reliable single-photon detection, with high quantum efficiency, low timing jitter and low detector noise. It provides a cost-effective solution for applications in which synchronous photon detection is essential, such as quantum communication and Quantum Key Distribution. It is also well suited to applications such as LiDAR where compactness is a key requirement.

The detector offers a gate input designed to avoid saturation or undesired detections and can also be operated in free-running mode.
The cooled InGaAs/InP avalanche photodiode and associated electronics have been designed to achieve especially low dark count and afterpulsing rates, even up to 100 MHz gated operations.

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