Why don't you just do a least squares fit of the reference curve?

You can have a look at mine if you want to. https://github.com/KAHR-Alpha/Aether You can put a beam as a source with a broad spectrum. But what are you trying to do exactly?

I'm not quite sure where this is going, but you might be interested in https://en.wikipedia.org/wiki/Extraordinary_optical_transmission

Unfortunately I don't have much spare time to split all the rays of a source point with and analyze the angles. Instead, here's the case of the beam at a 30 degrees angle, this should convince you I think. The output rays do seem to be quite parallel, although there's a small loss in precision:

Well, in this configuration things do seem to come out quite collimated: Here is the output of the sensor with respect to the rays orientation (x,y,z, normalized) : Here is the savefile if you want to play with it yourself:

When you read Born & Wolf's derivation of the thick lens, you see that the spherical aberrations come from the truncation of the power serie used to describe the interface, which then turns into a spherical surface. So it's not simply about how you combine them together. But I'm a bit confused...
