Hello community,
I will possibly need to simulate a cylindrical beam with ray optics. All optical surfaces are normal to optical axis, so it is going to be a simple astigmatic beam. While it is clear that the 2 curvature radii will be present in the equation of the surface of constant phase, I am not clear on the exact equation. Can anyone please suggest some reading materials? I am not entirely happy with what I currently have, as the solution is still unclear to me.
Thank you.

have you tried applying these to you beam, it is quite straightforward for truly astigmatic beams
