Inorganic Replication: Interpretation of Electron Micrographs

Source

In electron micrographs, just as in photomicrographs, the intensity variations which constitute the picture must be interpreted. The optical microscopist prepares his metal surfaces by etching techniques which experience has shown provide reproducible and interpretable photomicrographs. In the case of some alloys these techniques have been standardized. In the examination of metal and other surfaces, optical microscopy has very considerable advantages. Most important is the ability to scan large areas at relatively low power, then to select certain areas and observe them at higher power. Differences of color are also sometimes important. Control of the angle of illumination, combined when necessary with optical sectioning, permits determination of relative local elevations.
