How to use Jones matrices and vectors with ZOSPy?

[GBZH]

Hi,

first of all, many thanks for this nice Zemax Python interface.

Currently we are trying to code in ZOSPy a Faraday isolator as shown in:
https://community.zemax.com/people-pointers-9/how-to-model-a-faraday-rotator-isolator-3003

But we do not find how to set the parameters "A Real, ... D Imag " as shown in the attached screen capture of the example discussed at the link above. How to associate these parameters to a given surface?

Could anyone give an example on how to entirely code polarization/Jones'matrices in ZOSPy w/o importing any .zmx file?

Thanks a lot for any help.

Hi,

Thanks for your kind words, great to hear you found ZOSPy useful!
The parameters you want to set are specific to the object type, and are therefore part of the ObjectData property. Something like this should work:

my_nsc_object.ObjectData.AReal = 0.707

Let me know if this doesn't solve your problem, or if you've got more questions!

Thanks a lot for your help, we shall try to implement it.

If we were working in sequential mode instead, with the following code, obviously surfaces like J2 of type ILDERow do not have access to ObjectData:

J2= oss.LDE.InsertNewSurfaceAt(4)
zp.functions.lde.surface_change_type(J2, zp.constants.Editors.LDE.SurfaceType.JonesMatrix)
J2.Thickness = -5.00
J2.SemiDiameter = 5.00
J2.ObjectData.AReal = 0.707
J2.ObjectData.AReal = 0.707
J2.ObjectData.AReal = -0.707
J2.ObjectData.AReal = 0.707

Therefore how can one code the following setup directly in ZOSPy?

Thanks you again for any help.

Sequential mode works with surfaces instead of objects. Consequently, you can access these parameters through the SurfaceData property.
