When I perform FLIM-TCSPC measurements of a certain probe in solution or in a porous medium (polysaccharide substrate) I can fit the TCSPC data with only one term that corresponds to the expected

The system requires a 686 class PC with suitable USB host controller, 4 GB of memory, two or more CPU cores and at least 2 GHz CPU clock. The MultiHarp software is supported on Windows 8 and … FluoFit supports data files from the HydraHarp 400, PicoHarp 300, TimeHarp 260, TimeHarp 200, NanoHarp 250, SPC and MSA TCSPC systems as well as ASCII data files. Instrument response and fluorescence decay may be loaded from different sources or copied directly via the Windows clipboard (only for PicoQuant TCSPC modules). To celebrate the International Day of Women and Girls in Science we take time to catch-up with Angela Flack, our Applications Scientist.

The time-resolution can be obtained in a number of ways, depending on the required sensitivity and time regions. Edinburgh Instruments employs the technique called Time-Correlated Single Photon Counting (TCSPC), for Time-Resolved Fluorescence, which is used for the acquisition of single photons and allows for time resolutions in the range of picoseconds (ps) to nanoseconds (ns). The principle of TCSPC is the detection of single photons and the measurement of their arrival times in respect to a reference signal, usually the light source. TCSPC is a statistical method requiring a high repetitive light source to accumulate a sufficient number of photon events for a required statistical data precision. Fig 1. Time Correlated Single Photon Counting (TCSPC) has been one of the best ways of measuring fluorescence decay times since the method was conceived in 1961 by Bollinger and Thomas [1].

All TCSPC modules provided by PicoQuant expect standard TTL pulses for the external markers. This means 2-5 V for a logic “high”-level and 0-0.8 V for a logic “low”-level.

Time-correlated single photon counting (TCSPC) is used to analyze the relaxation of molecules from an excited state to a lower energy state.

Using time-correlated single-photon counting (TCSPC), temporal resolution of less than 25 ps has been demonstrated using detectors with a fall time more than 20 times longer. Here a general scheme for guiding external markers to the TCPSC modules will be illustrated by addressing the case of getting the markers from a controller of scanning module to the TCSPC module.

TCSPC systems provide outstanding sensitivity, but data acquisition can be quite time consuming. Another approach is the use of time-gated systems where the photons are detected during a fixed time window following the excitation [15] .

A few parameters are added in the parameter display on the left. TCSPC stands for time-correlated single photon counting. It is a method of using the timing of a pulsed excitation source, like a laser or LED, with the timing of the arrival of single photons on a detector to reconstruct the lifetime decay over many events (repetition of pulses and photons detected).

Data acquisition with PicoQuant TCSPC modules. The SymPhoTime 64 is the dedicated data acquisition software for PicoQuant's time-resolved confocal microscopes MicroTime 200 and MicroTime 100 and LSM upgrade kits. It can of course also be used with custom set-ups based on PicoQuant TCSPC electronics.

. It can be used as an imaging technique in confocal microscopy, two-photon excitation microscopy, and multiphoton tomograp All TCSPC modules provided by PicoQuant expect standard TTL pulses for the external markers. This means 2-5 V for a logic “high”-level and 0-0.8 V for a logic “low”-level. For more info about TTL signals see here.
