Objectives:

  1. Get familiar with Scanning Electron Microscope.
  2. Study SEM’s operating principle.
  3. Notice some SEM’s applications.

Introduction:

The Scanning Electron Microscope is a microscope that uses electron beam instead of light to form extremely larger with high resolution images.

Preparing the specimen for SEM examination:

In order to get clear and accurate results from this examination, the specimen should be prepared following these main steps:

  1. Removing all water, solvents or other materials that could vaporize during the operation.
  2. Firmly mount all the samples.
  3. Non-metallic samples, such as those of biology or ceramics, should be coated with some metals (usually gold) so they become electrically conductive.
  4. Metallic samples can be placed directly into the SEM.
