What Makes Electron Micrographs?

The original form of the electron microscope, the transmission electron microscope (TEM), uses a high voltage electron beam to illuminate the specimen and create an image. The electron beam is produced by an electron gun, commonly fitted with a tungsten filament cathode as the electron source.

What is the principle of electron microscopy?

Principle of electron microscopy

Electrons are such small particles that, like photons in light, they act as waves. A beam of electrons passes through the specimen, then through a series of lenses that magnify the image. The image results from a scattering of electrons by atoms in the specimen.

What is meant by electron micrographs?

noun. a photograph or image of a specimen taken using an electron microscope.
