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!
