First characterization results obtained with the help of OTF Studio Thin Film Software have been published:

An interesting paper on characterization of thin Al island films has been published. The reliable determination of the refractive indices, extinction coefficients, and thickness of metal island composites is a key issue in the practical integration of these films into multilayer coatings. This work  aims to study the optical properties of Al island films, deposited on quartz substrates using e-beam evaporation.

Three research groups were involved into the study. Three different characterization methods were used and the results were compared.  The effective optical constants of the Al island films are determined from spectral spectrophotometrical and ellipsometrical experimental data using: (i) a parameter-free dispersion model, (ii) a multiple oscillator model based on Gaussian line-shapes and (iii) $\beta$ distributed oscillator model. The details are in the publication.
