Importance of Condenser N.A.

By: plintilh

Condenser N.A. must at least match that of the objective to realize full resolution.

Object detail vs. acceptance angle

By: plintilh

The finer the spatial detail in an object the wider the diffraction angle - easily seen with a laser pointer and a fine grating.
