JEOL scanning electron microscope system
Description
A high magnification microscope with an illumination source that emits a stream of electrons. The electrons are focused by a magnetic lens to form a small beam that is rastered over a section of the sample. The electron beam causes secondary electrons to be emitted from the surface of the sample. These electrons are detected and imaged. Electron microscopes can provide magnifications up to 100,000 x.
