solved fluorescence measurements with TCSPC in-volves the following steps: First, the time difference between the photon event and the corresponding excitation pulse must be measured. For this purpose both optical events are converted into electrical puls-es. For the fluorescence photon this is done via the single photon detector mentioned before.

Using a laser pulsed at 40 MHz ( PDL-800-B ), the light intensity is reduced to the level where the photomultiplier detects a photon only after 1% of laser pulses ( i.e. , count rate <0.4 MHz). 2016-01-12 · Applications.

2016-01-12 · Applications. Fluorescence Lifetime Assays: The fluorescence lifetime is a robust parameter for use in several biological assays. It has the potential to replace conventional measurement techniques, such as absorption, luminescence, or fluorescence intensity. 3 Any change in the physicochemical environment of the fluorophore leads to changes in the fluorescence lifetime.

We present a novel, multi-dimensional, time-correlated single photon counting (TCSPC) technique to perform fluorescence lifetime imaging with a laser-scanning microscope operated at a pixel dwell-time in the microsecond range. We present an approach which monitors both time- and spectral information of the fluorescence in order to receive the full information content of the light emitted from a sample.
