The Quadoa Wave Optics Toolbox provides beamlet propagation methods that allow to simulate wave-optical phenomena like interference and diffraction or free space propagation of coherent beams as well as single- and multi mode fiber coupling.

@@quadoa Can you do a video regarding that it would be very beneficial to me

Yes, this is possible. If you need any help with setting up the merit-function please contact the Quadoa support.

There are organized Quadoa training seminars e.g. in Jena, Germany optonet-jena.de/events/master-optical-design/?lang=en . Quadoa offers free student licenses within the Quadoa Student Program. You can apply for a free student license here: www.quadoa.com/license-education

Unfortunately Apple discontinued official support for OpenGl which is required by Quadoa. So there won't be a MacOS version in the near future. It is however possible to run Quadoa in a Virtual Machine. We have successfully tested this on a Parallels VM but can't guarantee general compatibility

@@quadoa thans for information. Which mac model did you tested with wm parallel? On arm chip or intel?

@@cahitatlas Intel Core i5, but should also work on ARM chips

Quadoa can model fiber coupling efficiency, but not fiber propagation. Quadoa has an optical material library integrated.

I know, there’s not even a workable solution to eliminate sinusoidal deplaneration

😂❤❤❤❤😂😂😂😂😂

Hi Daargad, Thanks for the nice comment. The model is already included in the Quadoa telescope example folder. For further details please write a short mail to info at quadoa.com. Thanks

Yes sure, you can check out the microscope objective example files

@@quadoa Thank you. Where can i read off the value of the magnification? Please

@@lydiaewande8813 You can open the optical properties report under Analysis --> Reports

Quadoa is running on linux as well

@@quadoa Thanks, that's great! I'll try your demo version soon, looks like I need to upgrade my Linux box 🙂 The reason I asked about Buchdahl is that I wrote a program that calculates all of his aberration coefficients in full generality (any order, aspherics included, chromatic aberration coefficients, in any coordinates ("any" means "generalised paracanonical" in his terminology)). And I started playing with it and it's a rather interesting bag. High order aberration coefficients, like order 15 (Buchdahl would call it "order 7" as "n" for him means "order 2n+1" in modern terminology) can get very large, esp. with larger curvatures, a pattern already visible in his papers in which he calculates order 9 and 11 spherical aberration coefficients. But here is an interesting thing I ran across last week: I took a Zemax-optimised lens from the web and compared it to a Ludwig-Bertele-designed lens from US Pat. US3154628A (Example 4). Both are reasonably complex, 17 and 19 surfaces, respectively. Surprise: Bertele's design seems much better as far as the coefficients go. Even normalising for the larger surface curvatures, the difference in the coefficients is clear. I don't know what to think except being very impressed how Ludwig Bertele could do it with just logarithmic tables! And why Zemax wouldn't optimise better? Anyway, I thought this was interesting, sorry to talk your ear off.
