Amplifier-Discriminator
The CFD-2G is a hybrid amplifier-discriminator module designed for use with a wide variety of single photon detectors. It is neatly packaged to allow positioning close to the detector in order to minimise signal degradation, and features USB interface for simplified configuration.
Each module features:
The CFD-2G's unique combination of features makes it particularly well suited to applications involving low gain detectors where immunity to interference and signal degradation is a critical consideration. Its compact dimensions permit it to be close-coupled to MCP and NIR detection modules keeping the connection between the detector and the amplifier very short. Furthermore, since the amplifier and discriminator are on the same board, direct conversion to digital (NIM and TTL) means there is no requirement to expose the analogue amplifier output to an external connector.
A detector overload feature allows the programming of a count rate monitor threshold that can be used to deactivate the detector's high voltage supply in order to protect the detector from damage due to over-illumination. This feature operates in conjunction with the HORIBA Scientific Fluoro3PS HV power supply.
The CFD-2G is available in 4 variants optimised for different types of detector:
