Graticules as Guides in Electron-Microscope Metallography

ONE of the greatest difficulties for the user of an electron microscope in metallography is the localization of a micrograph on the original specimen. The high magnification gives a very small area of observation which is, in general, less than 15 µ × 20 µ. It is, for example, only one three-thousan...

Zusammenfassung:ONE of the greatest difficulties for the user of an electron microscope in metallography is the localization of a micrograph on the original specimen. The high magnification gives a very small area of observation which is, in general, less than 15 µ × 20 µ. It is, for example, only one three-thousandth of the area of a 1-mm. 2 specimen, and it is therefore practically impossible to identify it again.
