Modelling Wollaston prism

[Mwpdk]

Hello,
I’m currently working on simulating the geometrical setup of an interferometric device. My focus isn’t on replicating the underlying physical effects (such as interferometry, polarization, or fringe analysis), but rather purely on the geometry. The goal is to test alignments and evaluate how misalignments affect the instrument’s behavior.
I’ve developed some modules to emulate retroreflectors and beam-splitters, but I’m struggling to create a Wollaston prism. More specifically, its ability to split a beam into two diverging paths with fixed angles (I only need to emulate the beam directions for geometric purposes, not polarization).
Do you know if this is feasible within your library, or with any workaround?

It can now be constructed with Tools -> Other -> Custom Surface (even considering polarization)
