Ray Optics module : How to include opaque objects?

Hello,
I am trying to model the propagation of light in a system where there are light absorber (black metal parts), using the Ray Optics Module. However, if I assign an opaque material (such as copper) to an object, and set all its surfaces as Walls with the wall condition "Freeze", the Ray Optics solveer gives me the error that the index of refraction is not defined for copper; obviously it cannot be defined, since light cannot propagate through it.
How can I include objects with an undefined index of refraction in the domain of the ray tracing simulation?
Regards,
Louis H.

I have figured out the solution and thought I'd update my thread for reference.
The only domains that need to be included in the Geometrical Optics(gop) physics interface are the domains through which light will propagate (so, dielectric objects such as lenses, etc.).
Mirrors, diffraction gratings, absorbers, etc. should have the proper Boundary Conditions set in the gop interface, but they don't need to be included in the domain selection.
This is explained in the "Domain Selection" subsection, "Geometrical Optics" section, "Ray Optics Modeling" chapter of the Ray Optics Module User Guide.
