Detailed analysis of the reaction processes of molecules and crystals is growing increasingly important in various research fields, including photochemistry, polymer chemistry, biochemistry, and semiconductor physics. Accordingly, in addition to information accessible from normal spectra, there is growing need in fluorescence measurement to obtain information on the transient phenomena involved in fluorescent light emission by measuring and analyzing the fluorescence lifetime of the various substances.
The fluorescence lifetime is the period from the time at which a sample is excited to the excited state by the irradiation of pulsed light to the time at which the sample returns to its ground state as a result of the emission of fluorescent light. It is normally a value on the order of nanoseconds.
Based on its proprietary high-speed measurement technology, HORIBA developed the first domestic fluorescence lifetime spectrometer in the early 1980s, and has since enjoyed an excellent reputation in various research fields. |
