EBF Fit is a program for analysis of branching fractions of optical transitions. It can automatically calculate the branching fractions in measured spectra and fit them with theoretical model based on escape factor approach for description of self-absorption of radiation. Fitted fractions are used to determine the densities of lower states of optical transitions. It is developed at Department of Physical Electronics of Faculty of Science of Masaryk University in Brno. It is designed for Microsoft Windows 7 and higher.
