Hi Amrita,

I have follow-up questions:

  1. Locate the 3 .dll files lumhdf5.dlllumhdf5_hl.dll, and zlib1.dll in the install folder of Lumerical and copy them in the installation folder of Zemax

What exact folder should I copy to these dll's? I copied it to Zemax>DLL>Surfaces as in step 3. Is it correct?

  1. Open the file metalens_R10mm_f300mm.zprj and see how the metalens is defined

I have the lates Zemax Optics Studio, and when I am trying to open this file, the extension of this file is not in the list. How can I open this file in OpticStudio?
