Hi all,
I tried to figured out the difference between the chief ray definition by the classical books and the convention by ZEMAX.
the chief ray, by SPIE and Arizona University, is defined to pass through the center of the aperture stop. whereas, is defined to pass through the center of the entrance pupil. the difference causes a lot of troubles using ZEMAX. Can anybody explain this to me ?
