Lifetime fluorescence spectroscopy investigates the change in fluorescence over time of a sample when irradiated with UV, visible, or near-IR light. This decay in fluorescence can be measured over a wide time range: from picoseconds to milliseconds and beyond. HORIBA Scientific offers two types of fluorescence lifetime spectrofluorometers: time-domain (TCSPC) and frequency-domain. Our research-grade fluorescence lifetime spectrofluorometers are compact, benchtop or modular, customizable for any sort of fluorometry, be it fluorescence detection or phosphorescence studies that your research requires.
