snAPI
Brand: PicoQuant | Category: Nanotechnology
snAPI is a free Python wrapper for PicoQuant's time tagging and TCSPC electronics, backed by a high performance C++ core so that Python flexibility does not cost processing speed. Measurement classes cover Histogram for TCSPC distributions and lifetime analysis, Time Trace for count rate tracking, Correlation for auto and cross correlation such as g² and FCS, and Unfold and Raw for direct access to photon event streams. Real time manipulators handle coincidence detection across channels, herald based event filtering, channel merging, timestamp delays and sub-stream temporal filtering. It also supports White Rabbit multi-device synchronisation with sub-nanosecond precision, PTU file reading for offline work and photon number resolution, runs on Windows and Linux, and ships with ready to run quantum optics demonstration code including Bell states, GHZ, BB84 QKD and boson sampling.

More from Instrument Software
- SymPhoTime 64
SymPhoTime 64 is PicoQuant's integrated platform for time-resolved fluorescence imaging and analysis, pairing structured workflows with acquisition and processing tools. On the imaging side it unifies FLIM, FRET, anisotropy and multichannel imaging with decay fitting and IRF reconvolution. Its correlation engine covers FCS, FCCS, FLCS and antibunching analysis, and single molecule interfaces handle blinking, burst analysis, lifetime traces and PIE-FRET studies. The software controls PicoQuant microscope systems, the LSM Upgrade Kit, time tagging and TCSPC electronics and custom setups, with synchronised multi-mode imaging, real time previews and STUPSLANG scripting for tailored analysis routines and hardware extensions.
- QuCoA
QuCoA is an integrated acquisition and analysis package for PicoQuant time tagging and TCSPC electronics, aimed at experiments built around photon coincidences. It calculates g(2) antibunching correlations under continuous wave or pulsed excitation, with fitting models for single emitters with and without shelving states, pulsed excitation models and detector resolution corrections. Coincidence counting is defined through user set logical filters using AND, OR and NOT across detection channels and markers within configurable time gates. A scripting language allows custom analysis routines, and the software can be driven remotely over TCP/IP while acquiring and visualising data in real time.
- UniHarp
UniHarp is PicoQuant's free universal time-tagging data acquisition software for real time, high precision photon data acquisition, visualisation and first pass analysis. Complex measurements can be configured without scripting, and live results can be compared directly against previously recorded data. Auto-Tune adjusts key acquisition settings automatically from the detected signal, Curve Memory anchors or loads earlier curves for direct comparison with live data, and a customisable Scoreboard window keeps the essential acquisition metrics continuously in view. Built in filtering tools help clean measurement data.
