Hello! I'm new to OpticStudio, and I'm currently working on analyzing a microscope design that uses Grintech GRIN lenses. Whenever I open any of the files related to this project (including the Zemax file from Grintech's website), I get the error that the material GTAGNEU is not found in the SGRIN.DAT file (image attached). I have not been able to find any way to rectify this, and other people using the files don't seem to be having similar issues. I do have a student Zemax license, if that's relevant. Any help is much appreciated!

Hello Clark,

Where did you get another version of SGRIN.dat which contains GTAGNEU?  I met the same error!

Hello

I think you can find the SGRIN.DAT file on the Grintech website: https://www.grintech.de/fileadmin/user_upload/SGRIN_Rev_02-2015.ZIP

Hello Clark,


 


Ill like to have some discussion with you about using Optics studio for my research. Please are you available sometime soon?


 

Nevermind, it turns out I just needed to use a different sgrin.dat file.
