- How does the incident angle of a collimated beam relate to the output angle after passage through a two-lens system with f1=910mm and f2=40mm and Magnification=-f2/f1=.044?

I have 2 lenses. L1 and L2 with focal lengths f1=910mm and f2=40mm, respectively. They are separated by a distance d=f1+f2. The magnification of the system is M1=-f2/f1=.044. If I have a normally incident, collimated beam pass through my system I will have a beam, parallel to the optic axis exit the system, whose diameter is scaled by a factor of M1. I would like to know what happens if the incident beam is tilted at an angle theta? How does this incident angle relate to the output angle after passage through the second lens?

My initial thought was that the angle would also be scaled by a factor of M1, but I don't think this is right. Any thoughts would be greatly appreciated.
