Question

Why is the Huygens PSF obtained from a single lens in sequential and non-sequential modes different?

I simulated the Huygens PSF with the same spherical biconvex lens in both sequential and non-sequential modes, however, I found that they are not the same. I checked the wavelength of the system, the distance between the planes, but still can't find what the problem is, and I'd love someone to help me! The corresponding simulation file I have added in the attachment.

 

I would be very grateful if I could get your help.

You're at a slightly different distance from focus. List out the global coordinates in sequential mode, then compare them to your non-sequential coordinates.  There looks to be a slight difference.


Hello, Mike. Thank you very much for your reply. I am not familiar with many operations in Zemax, can you teach me how to list the global coordinates in sequence mode? Thanks again!
