Focus is a curve fitting software for the Windows operating system that has been developed to facilitate modelling of optical spectra and data exchange.

The architecture of its mathematical core 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.

Optical Spectroscopy markup Language
OSML is a XML-based language used by Focus to encode models and mathematical representations of optical functions.
