What Can Be Seen with a Scanning Electron Microscope

This technique allows you to see the surface of just about any sample, from industrial metals to geological samples to biological specimens like spores, insects, and cells.

What does a scanning electron microscope show?

A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. The electrons in the beam interact with the sample, producing various signals that can be used to obtain information about the surface topography and composition.

What specimen can be seen in scanning electron microscope?

A scanning electron microscope (SEM) can be used on thicker specimens, such as whole cells or tissues that have been fixed, dried, and coated with a thin metal film.
