Its an interesting practical demonstration of some technical aspects of getting your microscope up and running.

What is the magnification and resolution ?
She buys it used and does not show its top magnification, but she does show several values of magnification using a spent light bulb filament for a target. We never see what its capability is. With an electron microscope you ought to be able to see resolutions with .1 nm per dot. This length is called an angstrom and gets you near to an atomic scale though not quite. At this finest level of detail you should be able to see small groups of atoms and small crystal structures. There are newer instruments which can get you even better magnification of .5 angstrom, but an old scanning electron microscope is pretty good. A recent innovation is called the "Scanning Transmission Electron Holography Microscope."
