New TCSPC System Software Version 2.2 for PicoHarp 300

A new data acquisition software is now available for the PicoHarp 300 Time-Correlated Single Photon Counting system from PicoQuant. The new version 2.2 provides driver support for the 64 bit versions of Windows Vista. It also supports control for further monochromator models, permitting the automated recording of Time-Resolved Emission Spectra (TRES). The PicoHarp is based on an entirely new time digitizer with 4 picoseconds resolution, the shortest dead time of any comparable instrument, a processing rate of up to 10 million counts per second, and an extremely low differential non-linearity. It provides unique new features, notably two identical input channels that can operate independently, but with a common crystal time base. Therefore, not only classical TCSPC histograms for the measurement of fluorescence decays, but also picosecond coincidence correlations can be obtained.
