Secondary Electron Images
Secondary electrons are produced when the microprobe electron beam interacts with the sample surface, producing low energy secondary electrons that are detected by the secondary electron detector. A secondary electron image appears 3-dimensional. A well-tuned instrument can produce secondary electron images at magnifications of 100,000x.
