Hello,
Since I updated to 23.1, I have an issue with FftMtf analysis settings, which has no “Wavelength” attribute. You can see the error on the screenshot. The test script I am showing is a modified MTF ZOS-API example (PythonStandalone_04_pull_data_from_FFTMTF.py). This sample works ok by itself but fails if I try to add line 189 in the screenshot.
I tried to revert to 22.3 but it did not help. I am not 100% sure it is linked to the update.
Any ideas?

Hi Raphael,
I’ve seen this error several times now. I’m guessing you’re using a version of Pythonnet > 2.5.2. Try reverting to Pythonnet 2.5.2.
Take care,
David

Hi David,
Thanks a lot, it works! This also means we are limited to python 3.8 (I had upgraded to 3.9).
Does anyone at Zemax know if this will be corrected?
Thanks!

Hi Raphael,
I think Zemax is aware of the issue:
But what I don't know is if this is something they can fix or if the problem is with Pythonnet. Better ask Zemax themselves.
I must add that some stuff still works with more recent version of Pythonnet, but its quite inpredictable. In some projects, I use more recent versions of Python and Pythonnet, and it works fine. If anything, I would say the issue is mostly with analyses.
Take care,
David
Haha indeed, I was actually reading some of those, thanks for your help!
