Hi zemaxers
I am learning about birefringent materials, and my question is
How to confirm the focuses resulted by birefringent material at the same time?
the image expected is below

Sorry for bothering
Huygens PSF can deal with this issue
+2Hi Yang,
Yes, you found the solution I was going to recommend. Basically, using a Birefringent Surface is the same as using a multi-Config system and there are only a handful of analysis that support multi-config systems. Any ray based analysis can simply be superimposed in a multi-config system to provide the output, but if you need a diffraction based multi-config analysis, the Huygens PSF with Config=All is one of the most powerful tools that OpticStudio has. I would avoid any pupil-based calculations including FFT analysis because there is no “common” image-space reference point to superimpose the results onto a common plane.
