Long distance focusing telescope

I am trying to design a long distance focusing telescope (beam focus at 10 meters), My design is based on convex and concave mirrors (EFL : -100/400 mm) The distance between mirror should be 317 mm in order to obtain the beam focus at 10 meters. I use Comsol but I cannot see the converging of rays at long distance : I guess that Rayleigh distance is relatively so long. Someone knows how can I proceed to see the beam focusing at long distance ? Thank you
