Hi BC,
Well, you are using monochromatic light, while the standard used to determine such things, is the Rayleigh criterion at 0.000512 mm. This results in 571 lp/mm as the diffraction limit. It's really a bit of a moot point, I think, however. And I did get distracted in my discourse, too, yes.

A small point: 0.000512mm wave length is of course monochromatic light too, just of a different wavelength.
The one I used is the published one which was a wavelength used in real applications back then. Does not make much of a difference, just different diffraction limit numbers due to the different wavelength.
