Hi, I have a question with regards to how Zemax handles cylindrical/biconic systems. If I have a lens system where the say I have a pair of cylindrical lenses with two different focal lengths rotated 90 degrees about the light propagation axis, i.e. the system would have two different EFL, NA in the x, y axis, how does Zemax calculate parameters such as imaging NA, EFL, Seidel sums etc.? I noticed for example, for Seidel sums, Zemax does not break up the calculation of Seidel sums into two separate transverse axis but just gives one set of numbers. Zemax also gives the imaging NA, EFL data in the system data as one number instead of say two in two different axis. Is there a way to be able to get data for x and y separately? Thanks!
