Hello pam2r Users, hello Jacopo,

I passed the info about the libraries to the zemax support, they answered the following:

"
Thank you for providing more information. The libraries you mentioned look no problem to me.
Unfortunately we cannot debug for users’ DLL except the problem can also be reproduced with the built-in DLLs.
I would suggest you compare the nearest built-in code with your own code.
You can find the source code of these built-in DLL at \Documents\Zemax\DLL\Surfaces.
I think the problem is probably at your custom code.
"

Meanwhile, I was searching a little bit about where could be the issue.
I´ve compiled some info from other users, I put here the links.
If you can read these, maybe there is some clue there:

* Zemax manual, 18.1 ---> pages 332-333 (see attached to this e-mail those pages).
* In the zemax forum---> UserDefinedSurface(UDS)-DLL-Error --> http://forum.zemax.com/Topic4335.aspx
* In the zemax web of knowledg ----> How to debug a DLL or EXE ----> http://customers.zemax.com/os/resources/learn/knowledgebase/using-zos-api-how-to-debug-a-user-defined-dll
* Other users notes ----> Create a Zemax 64 bit DLL ---> https://texnical.wordpress.com/2014/07/23/create-a-zemax-64-bit-dll/

Have a nice weekend,

Hola! and thank you for your quick reply.
I will do 1) and 2) on Monday.
I will also try on Monday if I can load the pyramid in an old version of OpticStudio (from July 2021). So, I can write a more complete report.

Of course! I do quote the dll in our documents. Right now is mainly internal documentation, and the documents we share with ESO. I use this quotation:
"Jacopo Antichi et al. “Modeling pyramidal sensors in ray-tracing software by a suitable
user-defined surface”. In: Journal of Astronomical Telescopes, Instruments, and Systems
2, 028001 (Apr. 2016), p. 028001. DOI: 10.1117/1.JATIS.2.2.028001. "

I hope is correct. If not, please tell me.

It would be wonderful if I can contribute to the develop of the pyramid. For me, there is only advantages to be able to use the pyramid in the sequential mode... But you already know.
Ok, I do on Monday. For today, I finish.

Have a nice weekend,
conchi

Hola!

Loading the Zemax file inside pam2r web Page, with only 1 session opened, my OpticsStudio has no problems.

Reference for quotations Is fine!

I am out of ground based astronomy since 6years now, so no willing to re-enter. Too much topics in space technologies for me!

Please follow steps 1)&2) then Armando and Matteo Will help you. I am site of that!
