Petzval from Edmunds: Who wants to help?

Looking for ideas for putting together a 4x5 Petzval made from Edmunds Optics. I'm looking for general lens element sizes, perhaps someone has some general idea for the curves and diameter sizes. Thanks

Check out the WinLens software from Linos Photonics, the North American distributor for Rodenstock. I looked in to doing something similar a while back and found this program great fun even though I don't understand a lot of the optical engineering terms and charts. You can use the catalog numbers for singlets to automatically include elements, or if you can get enough information about the Edmunds elements you can plug that in.

Thanks for the software tip, judging by what I see on the Edmunds site, I should be able to make one using their lenses. Wish me Luck.
