Ansys Zemax OpticStudio can use an ideal phase profile to model the metasurface and then optimize it using ray tracing capabilities. Ansys Lumerical can then quickly generate its response on the nano-structure level. Based on this information, the metalens can then be accurately set in OpticStudio on a user-defined surface. All ray-based tools are available to assess the performances of your system.

The advanced tolerancing tools from Ansys Zemax OpticStudio include an easy-to-use surface irregularities option. It leverages the composite surface capabilities and uses Zernike sag data to model the surface irregularities, including for complex base shapes such as aspherical or many types of freeform surfaces. All other manufacturing tolerances can be added in order to assess your as-built performance yield.
