Fluorescence-lifetime imaging microscopy or FLIM is an imaging technique based on the differences in the exponential decay rate of the fluorophore from a sample. . 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. Time-correlated single photon counting (TCSPC) is used to analyze the relaxation of molecules from an excited state to a lower energy state.

Time-correlated single photon counting allows us to measure the time that a molecule stays in its excited state following excitation. An Introduction to Fluorescence Spectroscopy 7 Fluorescence At room temperature most molecules occupy the lowest vibrational level of the ground electronic state, and on absorption of light they are elevated to produce Comparison of the conventional fluorescence microscopy (A, D) with the fluorescence lifetime microscopy (B, E) together with the associated distribution of the fluorescence lifetimes (C, F). Convert Beker&Hickl, PicoQuant and other formats to Photon-HDF5 - Photon-HDF5/phconvert Photon counting is a technique in which individual photons are counted using a single-photon detector (SPD). In contrast to a normal photodetector, which generates an analog signal proportional to the photon flux, a single-photon detector emits a pulse of signal every time a photon is detected. The total number of pulses (but not their amplitude) is counted, giving an integer number of photons TCSPC can be used to measure lifetimes ranging from approx.

The MultiHarp 150 is an easy-to-use, plug-and-play multichannel event timer and Time-Correlated Single Photon Counting (TCSPC) device. Its extremely fast signal processing leads to an excellent data throughput via USB 3.0 interface. 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 Fluorescence lifetime and anisotropy decay data are acquired using a time-correlated single photon counting (TCSPC) instrument.

The lower limit is given by the jitter of the TCSPC electronics, while the upper limit arises from the time one can afford to acquire data with reasonable precision. Počítání fotonů je technika, při které se jednotlivé fotony počítají pomocí jednofotonového detektoru (SPD). Na rozdíl od normálního fotodetektoru, který generuje analogový signál úměrný toku fotonů, vydává detektor s jedním fotonem puls signálu pokaždé, když je detekován foton.
