This system canrealize the time-resolved measurement of transient fluorescence process. The key feature of this system is the application of TCSPC: 

The spectrum at the output of the spectrograph is projected on a 16‐anode PMT module. For each detected photon, the encoding logics of the PMT module deliver a timing pulse and the number of the PMT channel in which the photon was detected. The photons are accumulated by a multidimensional time‐correlated single photon counting (TCSPC) process.

TCSPC can be used to measure lifetimes ranging from approx. 5ps to over 50ms (over 7 orders of magnitude). 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. TCSPC Electronics.

The clock is started by the START signal pulse and stopped by the STOP signal pulse.

Time-correlated single photon counting (TCSPC) is a powerful method to accurately measure the fluorescence lifetime of samples. We use a TCSPC setup from Picoquant.Using a laser pulsed at 40 MHz (), 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). 2016-12-01 Lifetime-filtered FCS Ishii et al., 2015, “Lifetime-Weighted FCS and 2D FLCS:Advanced Application of Time-Tagged TCSPC” Gregor and Enderlein,2007 “Time Resolved methods in biophysics. 3.

Tidsupplöst fotoluminescens detekterades med användning av en tidskorrelerad singelfotonräkningsteknik (TCSPC) -teknik för mätning av spontant 

Optimization for brain activity monitoring with near infrared light in a four-layered model of the human head TCSPC, as any pulse technique, starts from the premise that the excitation pulse has the form of a  function, i.e. all intensity and no temporal width (see below). This means that the measured fluorescence response is that coming directly from the fluorophore. However, in reality this will not be the case. Time-correlated single photon counting (TCSPC) is a powerful method to accurately measure the fluorescence lifetime of samples. We use a TCSPC setup from Picoquant.

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 …

The DeltaPro™ TCSPC offers all of the benefits listed above in a new, stand alone, compact instrument. Plus you will have the benefit that your steady state fluorometer and your time resolved DeltaPro™ can both be used at the same time, dramatically increasing your labs productivity. Proven TCSPC technology with a proud tradition Time-correlated single-photon counting (TCSPC) has been the gold standard for fluorescence lifetime imaging (FLIM) techniques due to its high signal-to-noize ratio and high temporal resolution. The sensor system's temporal instrument response function (IRF) should be considered in the deconvolution procedure to extract the real fluorescence decay to compensate for the distortion on measured Training video on Time-Correlated Single Photon Counting (TCSPC) technique by Thomas Christian.DISCLAIMER:The information provided in the video is not a subs Ultrafast laser spectroscopy is a spectroscopic technique that uses ultrashort pulse lasers for the study of dynamics on extremely short time scales (attoseconds to nanoseconds).Different methods are used to examine the dynamics of charge carriers, atoms, and molecules. Many different procedures have been developed spanning different time scales and photon energy ranges; some common methods 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 … Principle of TCSPC FLIM. When TCSPC is combined with a scanning technique fluorescence lifetime imaging (FLIM) can be performed.

We found that our digitally implemented TCSPC (dTCSPC) provides a smart way of discriminating valid photon lifetime measurements were carried out using a time-correlated s-photon counting (TCSPC) ingle lifetime spectroscopy system with a picosecond pulsed diode laser (EPL-365 nm) as the single wavelength excitation light source. The PL spectra, at different temperatures, were recorded on a JY -U-1000 spectrometer using a LN 2-cooled CCD camera. HORIBA offers DeltaFlex TCSPC system, which is part of the Delta series of TCSPC lifetime instruments. The system measures luminescence lifetimes ranging over 11 orders of magnitude, and eliminates the need for changing cards or cables. TDCs formed by ring oscillators are arrayable, scalable, and low power, making them suitable for SPAD-based TCSPC 3D imaging systems.
