Hi all,

I also have a  very basic question on microscopy theory:

The Rayleigh criterion states that resolution d=0.61*lambda/NA. Taking 
the condenser lens into account this (in the textbooks) becomes d= 
1.22*lambda/(NAo+NAc). But shouldn't it be d= 0.61*lambda/NA with 
whichever NA is the smallest of the two?
