Software Utility for the Creation of Optical Function
Domingos DE SOUSA MENESESdesousa@cnrs-orleans.fr
Focus
is a curve fitting software for the Windows operating system that has been
developed to facilitate spectroscopic modelling and data exchange.
The architecture of its mathematical core, that mimics the way used by the optical spectroscopy markup language to encode spectroscopic models, is able to
construct sets of interdependent mathematical expressions and is thus perfectly
adapted for the reproduction and the solution of complex modelling problems
(infrared and Raman spectroscopy, impedance measurements,...).
Visual and non-linear least square curve fitting are among the numerous tools
implemented within Focus that contribute to accelerate the process of simulation.
