Olympus Fluoview FV1000 IX2 Inverted Confocal with FLIM Detector

This system is equipped with pulsed 405 and 485 nm lasers for FLIM. FLIM is the acronym for "Fluorescence Lifetime Imaging Microscopy" and is the technique that maps the spatial distribution of fluorescence lifetimes within microscopic images of fixed or living cells. The fluorescence lifetime measures the time that a population of fluorescent molecules spends in the excited state. The fluorescence lifetime does not change upon intensity variations and therefore lifetime measurements are not dependent on the local concentration of fluorophores, or variations in the optical path of the microscope, the local excitation light intensity, or on the local fluorescence detection efficiency.
