Hello,

I am modeling an OAP based image relay in zemax, and want to add a fold mirror in the relay. The relay adds zero wavefront without the fold and as soon as I try to fold, I get ~.2 waves of astigmatism that i can't seem to track down.

Any recommendations as to where this might be coming from is greatly appreciated! 😄
