Following Zemax tutorial, I add Marginal Ray Solve for my paraxial lens? What does it mean in practice? Also, my spot diagram has changed.
I am sorry if my questions sound very basic, but I a very new to Zemax. Could you also suggest some easy-to-understand materials that would helps in making a sense out of analysing graphs and diagrams produced by Zemax?

Every zemax window is having little blue question mark, you can refer to that for better undestading of that particular window.
