PicoQuant's wide range of products for photon counting includes several high-end modules for time-correlated single photon counting (TCSPC) and event timing, single photon sensitive detectors and specialized analysis software for the evaluation of (time-resolved) fluorescence measurements and quantum correlations.


PicoQuant offers several modules for Time-Correlated Single Photon Counting (TCSPC), Multi-Channel Scaling (MCS), coincidence correlations, or event timing with temporal resolutions between picoseconds and milliseconds. Single channel as well as multichannel versions with either USB or PCIe interface can be provided. Their high quality and reliability are expressed by a unique 5-year limited warranty.


The available photon counting detectors include photomultiplier tubes (PMT), Hybrid photomultiplier tubes and Single Photon Avalanche Diodes (SPAD). The detectors cover different spectral ranges between the UV and the NIR and are optimized for time-resolved applications.


PicoQuant offers specialized software for the analysis of quantum correlations and fluorescence measurements. This includes multiexponential fluorescence decay fitting as well as special methods like FLIM and FLIM-FRET, FCS, FCCS, FLCS, anisotropy, antibunching, coincidences and the analysis of fluorescence time traces.


Accessories for photon counting experiments include a router for the PicoHarp 300 TCSPC module, a specialized dual channel power supply for SPADs, a signal delayer with picosecond resolution and a trigger diode. Signal conditioners (inverter, attenuator, pre-amplifier or splitter) as well as signal cables can also be provided.
