Summary and References
This article has shown the basic Ray-aiming concept and its proper use in sequential ZEMAX. In summary:
- Only use Ray-aiming when needed
- Ray-aiming does not remove the pupil aberration but rather accounts for it when choosing input rays
- Ray-aiming with “float by stop size” system aperture type can be used to force the rays to fill the user-defined stop size
- Systems with decentered/tilted stop might require Ray-aiming

This article give me some hint to understand how ZEMAX works and also give me some questions, which puzzled me.
1. Optical engineer defines the stop surface and the system aperture, entrance pupil of the system is undefined by designer, how does ZEMAX know where is the entrance pupil located?
2. Ray aimed to paraxial entrance pupil or aimed to real entrance pupil is decided by Ray aimming on or off, i want to know how to calculate the real entrance pupil in ZEMAX?
3. what is the iterative ray tracing algorithm? Would please tell me where can i find some document about it?
