,Electron Beam—Specimen Interactions: Interaction Volume,res reduced below 10. Pa), the residual atom density is so low that the beam electrons are statistically unlikely to encounter any atoms of the residual gas along the flight path from the electron source to the specimen, a distance of approximately 25 cm.

SEM Case Studies, in ImageJ-Fiji can take the same members of the stereo pair and render the three-dimensional surface, as shown in Fig. 15.2, which can then be rotated to “view” the surface from different orientations (Fig. 15.3).

Image Defects,ed in the SEM literature. The examples described below are not a complete catalog but are presented to alert the microscopist to the possibility of such image defects so as to avoid interpreting artifact as fact.

Quantitative Analysis: From k-ratio to Composition,or associated with a family of characteristic X-ray lines (as is typically the case for energy dispersive spectrometers.) The numerator of the k-ratio is typically the intensity measured from an unknown sample and the denominator is typically the intensity measured from a standard material—a material of known composition.
