Calculation of ray angles through multilayers?

Question

Is it possible to calculate light emission angles, propagation angles, and paths through multilayer coatings?

Synopsis

Calculation of ray angles through multilayers?

Solution

Propagation angles are calculated throughout the optical design and are preserved through multilayer coatings. However, it is assumed that the thicknesses of multilayer coatings are thin enough that angular deviation or wavefront deformation is due to the coatings themselves is zero.
