I have sequential rays that enter a non-sequential component. In this element there are two sets of dffraction gratings helps rays to couple into the the medium and extract from the medium for analysis.
However, the rays I sent only diffract along the set primary diffraction order. Can Optistudio simultaneously trace multiple diffraction orders NS components?
Yes you can see multiple orders in non-sequential. Have a look at that sample file: '\Zemax\Samples\Non-sequential\Diffractives\Diffraction grating multiple orders.zmx'
