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


 Comparison of Refractive Indices/Extinction Coefficients Plots

OptiChar and OptiRe allows you to compare refractive indices and extinction coefficients on the same plot. This option is convenient when you wish to compare obtained optical constants with your previous results and values taken, for example, from Catalog or from various literature sources. 

In the right pane you can see comparison of refractive indices of TiO2 films deposited by three different deposition techniques.

Our experience in optical characterization and reverse engineering showed that this option in necessary and useful. See more in:
