  • Author: Stuart Thomson
Short lifetimes in the FLS1000 are measured using the time-correlated single photon counting (TCSPC) technique. The minimum measurable lifetime in TCSPC depends on the temporal width of the Instrument Response Function (IRF) which is a measure of the total response time of the TCSPC excitation and detection system. The width of the IRF is the key metric that determines the minimum measurable lifetime in the FLS1000. The FLS1000 can be equipped with a wide range of sources and detectors that enable IRF widths as low as 30 ps to be achieved.
