Transmission Electron Microscopy

==Basic Setup==
Uses electrons, which have wavelengths of 0.1nm - 0.2nm, which effectively gives them a higher resolution, about 1000 times better than ou​r lab microscopes.
A condenser magnet is used instead of glass lenses to distort the electromagnetic waves; glass lenses would insulate the electrons.
A projector magnet is used to project it onto a fluorescent screen because electrons are highly ionizing and would damage the human eye.
Electron microscopy takes place in a vacuum so that electrons can flow through; air would interfere with the flow of electrons
The resolution is 0.5nm or 5 angstroms (5 Å), which is extremely high.
==Appearance of Field and Object==
With nothing in the field of view, it will be very bright and white
The less dense the material, the less you see; the more dense the material, the more you see because there will be more electrons that will scatter, and so the material will appear darker
==Use==
Used to see smaller things than normal microscopes can see, like viruses and inclusions of bacteria. TEM can even see large molecules such as DNA and some proteins
