Description

All-in-one time-tagging, coincidence correlation and delay/pulse generation system. Observe detection rates for up to five single-photon detectors, generate up to four coincidence histograms between any pair of connected detectors or trigger signals, and record every arrival time for an exceptionally high number of detected photons, all with picosecond precision. Also a delay/pulse generator with four output channels of customizable and conditional pulses, allowing control and reaction to experiments and single-photon detectors in real time. Includes sophisticated internal processing for real-time conditional filtering to coincidence measurements, enabling direct recording of three- or four-fold coincidences without data post-processing or post-selection. Comes with new-and improved suite of LabView virtual instruments and Python scripts. Available in six combinations that are upgradeable at any time.
