Thank you.

Hi Samia,
This is quite a general question. I’d recommend reading about the DLL knowledgebase articles here to get familiar with this feature. Then, you can browse the sample files in you {Documents}\Zemax\DLL\Surfaces. If you have an equation which describes how the rays bend upon interacting with your custom surface, it should be possible.
Take care,
David

And check this sample file: "{Zemax}\DLL\Surfaces\us_grate.c"
We also had an “Ask an engineer” event about DLLs lately. The recording is available in the post:
