Radial Varying Coating

Coatings can be applied to any surface in FRED, with many different options available.  For specific solutions the user can define a general Script Coating which allows reflection and transmission coefficients to be computed based on ray position, polarization, angle of incidence, wavelength and the complex index of refraction of the incident and substrate materials.

Here the Script Coating is used to create a single layer ZnSe (zinc selenide) coating with radial thickness variation and is written to rigorously take into account polarization dependence and phase.
