Description
UniHarp is PicoQuant's universal data acquisition software for Time-Correlated Single Photon Counting (TCSPC) and time-tagging experiments.
Designed as an easy-to-use graphical interface, UniHarp allows researchers to configure PicoQuant timing electronics, acquire photon data in real time, visualize measurement results, and save or load experimental data. Its measurement framework preserves photon timing information, allowing the same acquired data to be used for different types of analysis—from conventional TCSPC histograms to advanced photon-correlation measurements.
The software supports several measurement classes, including Histogram, Time Trace, Correlation, Unfold, and RAW. Correlation measurements can be used for applications such as Fluorescence Correlation Spectroscopy (FCS) and second-order photon correlation g²(τ) measurements.
UniHarp also provides tools for working with data after acquisition. Functions such as Coincidence, Herald, Substream, Merge, and Delay allow researchers to select, combine, filter, or manipulate photon time-tag data for more advanced experiments and analysis workflows.
The software is compatible with PicoQuant's current time-tagging platforms, including HydraHarp 500, PicoHarp 330, MultiHarp 150/160, and TimeHarp 260 with the applicable DLLs. UniHarp supports configurations ranging from 1 to 64 channels, making it suitable for both compact single-channel experiments and large multichannel photon-counting systems.
