Deriving Numerical Aperture = N.A.
The geometries of diffraction patterns must match the geometries of acceptance angle.
Importance of Condenser N.A.
Condenser N.A. must at least match that of the objective to realize full resolution.
Fourier musical analogy
Complex frequency-based information can be decomposed into combinations of simple waveforms.
Object detail vs. acceptance angle
The finer the spatial detail in an object the wider the diffraction angle - easily seen with a laser pointer and a fine grating.
