Hello,
Is there a non-sequential implementation of the user defined surface US_LUNE.DLL, which implements the Luneburg lens concept?
Thanks for your help.
Cheers.

Hello myself,
Actually, I just happened to compile a GRIN DLL for non-sequential mode which does exactly that. You will find it attached to my reply. The archive contains the LuneburgGrin.dll, which needs to be copied in your \Documents\Zemax\DLL\GradientIndex. The OpticStudio archive file has a sphere using this GRIN medium. The only parameter the GRIN DLL needs is the sphere radius. There are no error verification in this DLL, so it needs to be the same as the radius defined in the sphere object. As shown in my screenshot below:

and here's the source code, for those interested 
Hi David,
Is there a way to reach you for help on my use of Zemax for GRIN simulations? I have read the manual, watched several videos and attended some webinars as well but I still need someone to put me through a couple of steps. Ill be grateful if you can assist.
Best,
ONO
