Looks pretty good, matching what Zemax shows using Gaussian apodization with an apodization factor of 2. A(r) = exp(-2*r^2)

I didn't participate in the previous thread on this. But in case it was of interest to someone, we get pretty much complete suppression of the Airy rings with an apodization factor of 1 (A(r)=exp(-r^2) ) without reducing the high frequency response nearly so much.

There is something missing in that formula? Why the factor 1 and the parentheses? Without that, this is just a Gaussian?
