Single photon detection module for 1064 nm

id Quantique has introduced the id400, the world's first photon counter for 1064nm. With a detection efficiency of up to 30%, this versatile instrument is truly invaluable for low light detection in this range.

The id400 single photon detection module consists of a detection head and a control unit. The detection head contains a cooled InGaAsP/InP avalanche photodiode (APD) optimised for 1064nm single photon detection and a fast sensing and quenching electronic circuit. The control unit is intended for APD temperature control and regulation, power supply, gate generation and dead time setting. It also provides BNC connectors for input-output signals and a USB interface for Labview communication. During operation, the detection head must be connected to the control unit with two coaxial and a DB9 cables. A +12V power supply that must connected to the mains is provided with the module.
