OptiLayer:  Your Partner in Design and Post-Production Characterization of Optical Coatings

 

All OptiRE options have been carefully tested on the sets of real measurement data. Results of out studies as well as methodology of the reverse engineering are published in our papers.

 Unique Non-parametric Characterization Model

Unique \(n(\lambda)-k(\lambda)\) characterization option assumes arbitrary but smooth dependence of refractive index and extinction coefficient on wavelength. These models should be used in most complicated cases. For example, when it is required to characterize thin films in wide spectral range and simple models (Cauchy, Sellmeier) are not suitable. Below we show fittings of experimental \(R/T\) data by model data and evolution of n-k wavelength dependencies. The data are related to TiO2 thin film on Suprasil substrate.

More complicated example can be found here. Further details and mathematical formulas can be found in our publications.
