By definition, Microscopy is research using microscopes.
Therefore we should become familiar with the names of the microscope parts,
or at lest, we should know the difference between an objective lense and an ocular lense.
I only use light microscopes, because electron microscopes and X-ray microscopes are too expensive and not needed for the things I look at.
Here is a good image of a light microscope with the names of their parts:


I do not have a microscopes used to look at 3 dimensional objects, because must of the time I look at samples of my blood, my sputum, or some cultured pathogen or microbe.

In the World Wide Web (a.k.a Internet) you can find a lot of data about microscopy.

There is a free, and very good, microscopy magazine from Austria called "Microbe Hunter"
Here is a link to it:
