This video was made as a part of the ELEC 571-Imaging at the Nanoscale course by TCSPC Modules • Electrical Time Resolution down to 8 ps FWHM/5 ps rms • Minimum Time Channel Width 820 fs • Total useful count rate up to 4 MHz • Measurement times down to 1 ms: Lifetime Measurements Range: 10-11 sec to 10-2 sec: OS Requirements: Windows 10: Power Requirements: Universal power input: 110-240 V, 50/60 Hz, 400 VAC: Dimensions 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 Figure 2: TCSPC setup for fluorescence lifetime imaging (FLIM).

Becker and Hickl products include photon counters, time correlated single photon counting (TCSPC) cards, detectors, sampling modules, diode lasers, lock-in amplifiers, delay generators and amplifiers. These systems are integrated into fluorescence systems and laser scanning microscopes for fluorescence resonance energy transfer (FRET) and fluorescence lifetime imaging (FLIM). M 1 can also be interpreted as the average arrival time of all photons within a TCSPC measurement. It is thus linearly related to the time-constant of a single-exponential sample response, e.g. the lifetime of a single-exponential fluorescence fluorescence and phosphorescence lifetime images in laser scanning systems. It is based on modulating a high-frequency pulsed laser synchronously with the pixel clock of the scanner, and recording the fluorescence and phosphorescence signals by multi-dimensional TCSPC. Fluorescence is recorded during the on-phase of the laser, Conventional TCSPC (O’Connor and Phillips, 1984) is a one-dimensional technique, i.e., it records the pho-ton density vs.

2015-05-01 · TCSPC FLIM has a number of other features important to lifetime imaging of biological systems: It is able to resolve complex decay profiles and it is tolerant to dynamic changes in the fluorescence decay parameters during the acquisition (Becker, 2005, Becker, 2014).

Axel Bergmann. The fluorescence lifetime values amount to 4184 ps (71 ps FWHM) for GOI, 4121 ps (123 ps FWHM) for p-TCSPC and 4049 ps (98 ps FWHM) for the single-channel TCSPC, which corresponds with published results, i.e. 4080 ps. Time-correlated single-photon counting (TCSPC) is a well established and common technique for fluorescence lifetime measurements, it is also becoming increasingly important for photon migration measurements, optical time domain reflectometry measurements and time of flight measurements. The principle of TCSPC is the detection of single photons and 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.
