I have measured the surface deviations of a 16mm diameter lens with a Zygo running on MetroPro and have exported a 37 term Zernike Fringe Sag data table. When I enter the Zernike Fringe Sag coefficients directly into OpticStudio the magnitude of the resulting transmitted wavefront error is appropriate to the expectation based on the surface error but the Normalization Radius was left defaulted to 100 in OpticStudio and was not set to match any corresponding radius value in MetroPro. If the Norm. Radius is changed the resulting wavefront changes but not in any way that makes sense with regards to the Zygo measurements or expectation.

Is there a method to set the Normalization Radius in OpticStudio such that Zernike Fringe Sag data imported from MetroPro can be correctly used to model an as-built lens? Could the MetroPro output also assume a Normalization Radius of 100?
