The Mini- (Mini-tau) Research / Q.A. / Teaching Spectrometer 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 or 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. The Fluoracle Software supplied with the Mini-tau has an easy-touse interface and allows users to comprehensively record data and accurately analyse complex decay kinetics of up to 4 lifetimes. Mini-tau Product Features: • sample chamber with source and detector, A PC and electronics plug-in board • ulsed LED or picosecond diode laser (with choice of P wavelength) • ntegrated electronics with repetition rate up to 20 MHz I • ltra-fast, blue or red sensitive single photon U counting PMT • luoracle Windows application software for F comprehensive data acquisition and
