(xo,f(xo)) gives the Point where the Ray meets the upper surface of the lens. It would be enough for me if it would be possible somehow to make a table of this xo's. So that several rays meet the lens at the upper surface. But I don't understand how this would work together with the With command. All the other variables /theta2, xe, ye, xu follow from the x, y and xo values. URL: ,
