EI FAST is a data analysis software suite from Edinburgh Instruments Ltd. designed for processing and interpreting time-resolved and steady-state photoluminescence measurements. Built for researchers who need reliable, quantitative insights from complex optical datasets, it provides an efficient workflow from data import to publication-ready results.
The software offers advanced fitting and modeling for fluorescence lifetimes and kinetics, including multi-exponential analysis, iterative reconvolution with the instrument response function (IRF), global analysis across multiple datasets or wavelengths, anisotropy and rotational correlation analysis, and lifetime distribution modeling. Fit quality is easy to assess through residuals, reduced chi-squared, and autocorrelation plots, while parameter constraints, confidence intervals, and batch processing support rigorous and repeatable analysis. EI FAST integrates smoothly with Edinburgh Instruments measurement systems and supports common data formats for flexible import and export.
Whether you are studying excited-state dynamics, energy transfer, quenching, or other photophysical processes, EI FAST helps you extract accurate parameters and produce clear, publication-ready figures and reports with confidence and speed.
EI FAST is developed by Edinburgh Instruments Ltd.. The most popular version of this product among our users is 3.5. The name of the program executable file is FAST.exe.
