id400 1064nm Photon Counter

id400 1064nm Photon Counter

id Quantique's id400 is 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.
