Numerical aperture revisited
N.A Plus immersion oil
Using the 550 nM full wave compensator
Fourier musical analogy
Complex frequency-based information can be decomposed into combinations of simple waveforms.
Importance of Condenser N.A.
Condenser N.A. must at least match that of the objective to realize full resolution.
Cell wall between crossed polars
Numerical Aperture vs useful magnification
A quick estimate of useful magnification:
N.A. X 1000.
Zero order has no information
Spatial information is encoded in the diffracted rays.
