TCSPC (Time-Correlated Single-Photon Counting) is the method of choice for fluorescence lifetime measurements. The TCSPC technique outperforms all other techniques in sensitivity, dynamic range, data accuracy and precision. Time Resolution: TCSPC provides the highest time resolution among tech - niques using single photon detectors. This distinguishes it from up-conversion, autocorrelation … Multispectral fluorescence lifetime imaging by TCSPC. Becker W(1), Bergmann A, Biskup C. Author information: (1)Becker & Hickl, Nahmitzer Damm 30, 12277 Berlin, Germany. becker@becker-hickl.de We present a fluorescence lifetime imaging technique with simultaneous spectral and temporal resolution.

What is TCSPC? Red-Edge Excitation Spectroscopy of Proteins with the FS5 Spectrofluorometer. Möchten Sie mehr über Edinburgh Instruments erfahren? Bleiben Sie auf dem Laufenden mit den neuesten Nachrichten und Produktinformationen. Fluorescence lifetime is a significantly more robust measurement of FRET, increased FRET transfer reduced donor lifetime, which can simply be recorded with TCSPC-FLIM. This type of measurement is advantageous as it requires low excitation light levels, it is oblivious to donor concentration, and in addition it provides information about the ratio of interacting versus non-interacting proteins TCSPC .

the emission lifetime. TCSPC is based on light behaving as quanta (photon). TCSPC has many applications other than fluorescence lifetime measurement, such as Ultrafast recording of optical waveforms, Detection and Identification of Single Molecules, DNA sequencing, Optical Tomography, and Fluorescence lifetime imaging .

A new Time-Correlated Single Photon Counting (TCSPC) imaging technique delivers combined intensity-lifetime images in a two-photon laser scanning microscope. The sample is excited by laser pulses Fluorescence Lifetime. Fluorescence Lifetime Imaging Microscopy (FLIM) Förster Resonance Energy Transfer (FRET) Fluorescence Correlation Spectroscopy (FCS) TCSPC(Time Correlated Single Photon Counting) module can be used for this system and it can measure the fluorescence lifetime from nano second to micro second. And, by combining the high sensitivity CCD detector for spectra, and a high performance monochrometer, it can mesure also fluorescence-spectrum PL measurement and PLE measurement. This paper describes a time-correlated single photon counting (TCSPC) technique for picosecond resolution multi-wavelength lifetime imaging in two-photon or confocal laser scanning microscopes and other scanning systems. the emission lifetime. TCSPC is based on light behaving as quanta (photon).

Lakowicz, redakt¨or, Principles of Fluorescence Spectroscopy, ss 1–26, 97–155. Springer US Fluorescence Lifetimes with TCSPC What is fluorescence lifetime spectroscopy Lifetime fluorescence spectroscopy or time-resolved fluorescence spectroscopy investigates the change in fluorescence over time of a sample when irradiated with UV, visible, or near-IR light. fluorescence lifetime measurement. Only one photon is processed at a time, so the light pulses required for sample excitation have low pulse energy. This causes minimal sample degradation and avoids many non-linear sample effects.
