Objectives:
- Get familiar with Scanning Electron Microscope.
- Study SEM’s operating principle.
- 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:
- Removing all water, solvents or other materials that could vaporize during the operation.
- Firmly mount all the samples.
- Non-metallic samples, such as those of biology or ceramics, should be coated with some metals (usually gold) so they become electrically conductive.
- Metallic samples can be placed directly into the SEM.
