• Luminosa PDA-23 Add-On: The PDA-23 add-on equips the Luminosa confocal microscope with a cooled 23-pixel SPAD array for confocal time-resolved detection, combining the higher resolution of image scanning microscopy with quantitative FLIM. Pixel reassignment raises resolution by about 30%, taking 485 nm excitation down to 155 nm FWHM, and deconvolution takes that further to 120 nm FWHM. Computational sectioning improves contrast by rejecting out of focus light, and every pixel of the array is time tagged, with dual-channel acquisition available simultaneously through pulsed interleaved excitation. Integrated in Luminosa, the detector keeps alignment stable and pairs with the MultiHarp 160 multichannel time tagging and TCSPC unit, with analysis handled in NovaISM.
• MicroTime 200 STED Add-On: This open STED add-on extends the MicroTime 200 to super-resolution imaging with time-resolved contrast, resolving nanoscale structures below 50 nm that confocal images cannot separate. A stable donut shaped depletion beam is produced by an EASYDOnut phase plate, which avoids complex alignment, and gSTED time gating isolates late photons for better resolution and sensitivity. Triple-species STED imaging is possible using fluorescence pattern matching for accurate multicolour co-localisation, and the reduced observation volume benefits STED-FCS by allowing diffusion measurements at higher concentrations. Full compatibility with the MicroTime 200 is retained, and the complete STED workflow including time gating and multi-species pattern matching runs in SymPhoTime 64.
• EasyTau 2: EasyTau 2 brings hardware control, data acquisition and analysis for PicoQuant spectrometer systems into a single time-resolved fluorescence workflow. Three operating modes are offered: a Wizard mode with guided step by step workflows, a Customized mode giving full manual control of hardware and acquisition parameters, and a Scripting mode for automated measurement routines and remote execution. Analysis covers multi-exponential decay fitting up to 5th order, lifetime distribution models including Gaussian, Lorentzian and stretched exponential, anisotropy analysis from polarisation resolved studies, global and batch fitting across multiple datasets, bootstrap error analysis with confidence intervals, and IRF corrected reconvolution fitting.
• NovaFLIM: NovaFLIM is PicoQuant's analysis software for fluorescence lifetime imaging, with GPU acceleration applied to FLIM, FLIM-FRET and anisotropy data. Analysis modes span fast lifetime determination, multi-exponential decay fitting, phasor plots and pattern matching for species separation and multiplexing, alongside FLIM-FRET analysis and anisotropy imaging. Batch analysis handles z-stacks, time-lapse series and stitched images, and ROI selection can be made reproducible using histograms of the fitted parameters. ISM-FLIM is supported in combination with PDA-23 SPAD detection.
• NovaISM: NovaISM is image scanning microscopy and FLIM analysis software that is integrated with the Luminosa microscope and optimised for the PDA-23 SPAD array detector. Working from the summed signal of all 23 SPAD pixels, pixel reassignment alone raises resolution by roughly 30%, and combined with computational sectioning and deconvolution the software delivers up to 1.7 times higher resolution than conventional confocal imaging. Computational sectioning removes out of focus contributions to lift contrast, and it can run simultaneously with lifetime species separation. Raw time tags from all 23 PDA-23 pixels remain accessible, batch analysis covers series measurements and multi-ROI workflows, and results export as BMP, PNG, OME-TIFF and SVG.
• 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.
• snAPI: 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.

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.
• 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.
