Angle vs height plot

[BuergiR]

I was missing a field-angle-vs-height plot as available in Zemax in the analysis class. I needed this plot to visualize the angle error of a telecentric lens in degrees. Depending on the lens setup, this plot must be drawn across the pupil field or across the image field.

For this purpose I wrote two functions. I am well aware that the implementation is not very good and the functions are not excessively tested. But maybe this can give ideas for a regular implementation.

This convinced me that Optiland is very versatile and may be the open source optic tool many were looking for. Thank you for all your work!

Hi @BuergiR,

Thank you for sharing this!

The idea of a field-angle-vs-height plot is a great addition, especially for applications like evaluating telecentricity. I think this fits well within the analysis module, perhaps as part of a new submodule.

I'd like to adapt your code slightly to align with the interface style of other analysis functions. You’ve already done 90%+ of the work, so integrating it should be quite straightforward.

I’ve added this to the to-do list, and I expect we can finalize and merge it in the near future.

Thanks again for the contribution and for the kind words about Optiland!

Best regards,
Kramer

Hi Harrisson

Thank you for considering this plot! Cool, so it will also help others.
Of course you will have to implement it in the sense and spirit of optiland and fix all the bad programming. That will for sure take some time.

Best regards

Hi @BuergiR,

I just finalized the implementation of the angle vs. height analyses - see #215 or an example here. I largely used your code, but restructured it for compatiblity with Optiland. I also added you to the authors page. If you prefer not to be there, just let me know and I'll remove you.

I will close this discussion now, but can reopen it later if needed.

Thanks again!
Kramer
