Time interval and frequency counter PicoQuant

The HydraHarp 400 is a high-end, easy-to-use, plug and play Time Interval Analyzer (TIA) and Time-Correlated Single Photon Counting (TCSPC) system with scalability for multiple channels*. Dependent on the chosen frame size up to 4 or up to 8 channels can be installed. It is connected to a PC through a USB 2.0 high speed interface. It provides identical synchronized but independent input channels. They can be used as detector inputs for coincidence correlation experiments as well as independent stop inputs for TCSPC. A dedicated common sync input is provided for TCSPC with fast excitation sources. This allows forward start-stop operation at the full repetition rate of mode locked lasers with stable repetition rate up to 150 MHz. Experiments with low repetition rate benefit from the HydraHarp's multi-stop capability.
