Hi Guys! I am unable to reverse the elements for it to point properly (Labelled in diagram below). It seems like the path is being reflected back to the original path and I do not know what to do. Any help will be great, thank you so much!

Hi there!

It seems like you only attached the session file (.ZDA), if you can include the lens file as well (.zos) one of us can take a look at your set up. 

Oh ok! Sorry for the inconvenience!

No worries! 

Taking a look at your Multi-Configuration editor, it seems that you did address the positive or negative thickness values that are dependent on whether the rays/configuration was being reflected or transmitted through the beam splitters. The same was needed for the elements whose orientation needed to be reversed.

I went ahead and made the modifications to the MC Editor to reflect the orientation changes in the two configurations. I multiplied the lens curvature, thickness, and aspheric terms by *-1 to reflect the direction of propagation of the two configurations to match the others. 




Let me know if you have any questions or concerns, I recommend reviewing the updated attached file to ensure the orientation of the lenses/thicknesses are correct for your application and analysis.
