A method of observing selected areas in electron and optical microscopes

Abstract

A technique enabling systematic observations of metallurgical features in the electron microscope is outlined. Such features of interest are suitably marked; and wet stripped plastic replicas are prepared in the normal manner. A simple apparatus, briefly described, allows one to position these replicas on electron microscope specimen grids as desired. This permits direct comparison of electron and photo micrographs of any surface detail. In addition, changes in surface detail or of a given feature in depth may be followed.
