I’m using a lens that on both sides is Toroidal. When making Physical optics propagation, what are the things I need to be aware of in order to make a correct propagation? One thing I noticed is the ‘Separate X-Y’ , any other issues?

POP simulation using Toroidal lens
Best answer by David
Hello,
Separate X-Y is certainly appropriate for a toroidal lens. The POP display looks a lot like the intense core of the spot diagram. Perhaps the wider features in the spot diagram would be visible in the POP analysis if the POP field was enlarged and displayed with log scaling.
There are people on this forum who have more POP knowledge than I. Perhaps we will hear from them.
Thank you David, I’m asking particularly about Toroidal since it has no radial symmetry and I see some strange behavior when doing POP. I thought that the non symmetry could be the reason
The geometric ray trace spot footprint is totally different from the POP
POP spot height is about 3.4mm while geometric is 16 micron
