Hi
I am trying to design a three mirror off axis telescope. The free parameters are the offset between the apertures and distance betwen the surfaces.
My question is for a system with 'n' elements/surfaces (n=3 in my case) is there a relation between optical path length and focal length of the system.
I don't want to go too descriptive about this problem. If it might help I can upload a pic in some webpage.
