Reply To: Pupil position solve does not work

[Berta Bernad]

Hi Jurgen,

The Pupil Position Thickness Solve can be used to locate the Exit Pupil position using real, differential rays rather than paraxial rays. Since the exit pupil is calculated as the image of the aperture stop in image space, it doesn't make much sense to use this solve before the stop (And that's why the solve there is not doing anything). 

You can have a look at the article “Display pupils on a layout plot – Knowledgebase”. Though I don’t think the content in the article applies specifically to the analysis you’re trying to do, it does at least demonstrate the quantities that OpticStudio reports as the Entrance and Exit Pupil and how those are determined within the software.

Best,
