Time-Correlated Single Photon Counting (TCSPC) facility is a sophisticated equipment setup used in various fields of research, such as biophysics, quantum optics, and material science. TCSPC enables precise measurement of ultrafast optical events and fluorescence phenomena with picosecond time resolution. This facility utilizes advanced photon counting techniques to capture the arrival times of individual photons emitted by a sample. By correlating the arrival times of these photons, valuable information about the sample's dynamics, fluorescence lifetime, and other related properties can be extracted. TCSPC offers a powerful tool for studying fast kinetic processes and is vital for numerous applications in both fundamental research and applied sciences.
