For baffles, you want to take one side of the EP and go to the previous
surface and so forth at the same side edge.  This insures that you have a
100% illumination of the EP in the end. Before you do this tho, you have to
know how big the surfaces need to be and this is done by finding the FOV
that the EP can see and calculating the size needed to meet that FOV at
each stage.  Simple trig is all that is needed for this job.
