30 Mar 2009 Single photon detection module (spectral range from 900 to 1150nm ), based on InGaAsP/InP avalanche photodiode operating in Geiger mode. The id400 single photon detection module consists of a detection head and a control unit. The detection head contains a cooled InGaAsP/InP 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. |
