I didn't follow the link but if you'd be curious to do some ray tracing of designs like this :

52mm f/2 for Nikon F mount

Then contact me by email or Private Message (PM).

Sorry, what do you mean by "Ray Tracing?" Will I need special software to do that?

Ray tracing is sending light rays through an optical prescription like the blue and green rays above. (That optical prescription is from a patent.)

There's a way you can use my software especially for something so simple but I would have to lead you through the process.

It could be helpful to confirm things like distances depending on what other resources you have.
