A method to derive the concentration profile directly by the refractive index profile measurements was developed for binary silica glasses. Using the Lorenz-Lorentz relation, it is possible to derive the molecular electronic polarizability values at 632.8 nm from the RNF measurements on fibres and EDS concentration measurements on preform discs. Substituting these values a direct relation between the refractive index and the molar fraction can be obtained. A good agreement between the concentration profile derived with our method and the EDS results was observed.
