Code V considers the top and bottom surfaces of a lens as independent entities. You must attach the generated surface interface files to the corresponding surface in Code V. Attach the birefringence interface files to the top surface in Code V.
Note: Meniscus lenses with a bevel effectively have a smaller diameter for the concave surface than for the convex surface. You may need to run the mpi2codev.vbs script twice, specifying the diameters for the top and bottom surfaces, and import the corresponding version into Code V on each surface.
If you are analyzing a multi-lens assembly, repeat the process for each lens.
