What are the common types of electron microscopy?

Common types of electron microscopy include transmission electron, scanning electron, and reflection electron microscopy. 

1. Electron transmission microscopes use accelerated beams of electrons (through electromagnetic lenses) to produce a highly magnified image.
2. Scanning electron microscopy uses a method called raster scanning to generate detailed images of the sample.
3. Reflection electron microscopy uses a stream of electrons which bounce off the sample when it is observed.
