Good afternoon,

After generation of the near field .zbf file in Lumerical and opening it in the zemax environment under the Physical Optics tab, i am not certain how this near field relates to the rest of the optical elements i have in the Zemax file. Let's take, for example, a simple asphere. If i want to insert a metalens behind the asphere, how do I do that. I have the near field file from Lumerical. I have the asphere in Zemax. The steps in between are a bit fuzzy for me. How does one assess the overall performance of the combined metalens and conventional optics hybrid design? I’d like to ultimately use the same standard optical engineer figures of merit for image quality like MTF. Any help would be greatly appreciated. thanks!
