This first posting of this new series covers the "Sharpness Index" — a simple means for comparing the relative performance potential for objectives of differing Magnification and NA.
The method presented is more inclusive of important optical parameters (e.g: both Magnifiction and NA) and is thus potentially more useful than the simpler "Rayleigh criterion," which has become so over-used and mis-applied these days. ("Rayleigh," and more modern alternatives, will be covered in a future post.)
As before, the document itself is presented as a .pdf file, to facilitate downloading, printing and off-line archiving.
I hope you enjoy this information and benefit from it...
