Can someone point me to a model using a VIPA (Virtually Imaged Phase Array)? I keep getting tangled up in transitions from pupil to line focus to image, and I think someone must have figured out a better way. For reference, https://lightmachinery.com/optics/custom-optics/vipas/.
Thanks,

Hey Eric,
It’s not quite clear to me how the VIPA is different to a Fabry-Perot etalon, but etalons are easily modeled using the coatings capability in OpticStudio, in both seq and NS modes. Check the sample files at Documents\Zemax\Samples\Sequential\Polarization for Fabry-Perot examples. If you could clarify the difference between a VIPA and a Fabry-Perot etalon, I’d be grateful
