The Mini-tau is an ultra-compact, low cost, filter-based dedicated fluorescence lifetime spectrometer. Using the Time-Correlated Single Photon Counting (TCSPC) technique, the Mini-tau can measure fluorescence lifetimes ranging from 25 ps to 10 μs*. It can also be equipped with Multi-Channel Scaling (MCS) electronics for long-range photoluminescence from 10 ns to 10 s.
Whether you need to measure fluorescence lifetimes of time-resolved fluorescence anisotropy for research, quality assurance or teaching applications, the Mini-tau is the ideal all-inclusive, fully-integrated solution. The Mini-tau measures fluorescence lifetimes after numerical reconvolution based on the established Marquardt-Levenberg algorithm.
