• Ultra compact filter-based fluorescence lifetime spectrometer
  • Short Lifetimes ranging from 25 ps to 50 μs
  • Integrated electronics with repetition rates up to 100 MHz
  • Ultra-fast blue or red sensitive single photon counting PMT for ultimate sensitivity
  • Fully comprehensive data acquisition and analysis

The Mini-tau is an ultra-compact, low cost, filter-based fluorescence lifetime spectrometer for lifetimes ranging from 25 ps to 50 μs*. Using the Time-Correlated Single Photon Counting (TCSPC) technique, the Mini-tau is supplied with our F980 software and a USB connected TCC2 electronics module to enable fast, reliable, and accurate measurement and data analysis.

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.

The F980 software supplied with the Mini-tau has an easy-to-use interface and allows users to comprehensively record data and accurately analyse complex decay kinetics of up to 4 lifetimes.

*Minimal lifetime resolution is laser dependent.

F980 spectrometer operating software is at the heart of all our fluroescence spectrometers and is a fully comprehensive, user-friendly data analysis software package. Irrespective of system configurations, this software provides the user with complete control.

The F980 software is Windows 7, 8 and 10 compatible and is based on a data centred design that enables the user to focus on their measurement. This guarantees ease-of-use in the operation of a modular and potentially complex spectrometer.

Measurement set-up and data acquisition is made through an intuitive menu system. Key spectroscopic parameters are easily accessed through functional groupings, while common measurement routines can be saved as method files to allow previous experiments to be easily repeated. Tabbed dialogue boxes and particular scan parameters are always visible during set-up. The current status of the instrument is also continuously displayed.

A unique feature of the F980 software is that all modes of data acquisition, including spectral scanning and lifetime acquisition in both MCS and TCSPC modes, are controlled from within one software package. Modern light sources, detectors, complex sample holders (plate reader, XY sample stages, titrator) and cooler options (thermostated sample holders and cryostats) are supported and fully software controlled.
