The spatial resolution of scanning Auger microprobe systems Is now equivalent to most scanning electron microscopes. High magnification secondary electron Images or absorbed current images are a routine part of the data from such systems. Quantitative Aspects of AES... 

The very high powers of magnification afforded by the electron microscope, either scanning electron microscopy (sem) or scanning transmission electron microscopy (stem), are used for identification of items such as wood species, in technological studies of ancient metals or ceramics, and especially in the study of deterioration processes taking place in various types of art objects.

Each specimen was dehydrated, infiltrated and embedded in Technovit based methylmethacrylate. One section was cut and around in preparation for scanning electron microscopy (SEM). In each case, three overview photos were necessary and four high magnification fields (40X) were photographed and digitized. These fields were later analyzed for volume fraction of soft tissue, bone... 

Scanning electron microscopy (SEM) can produce images of surface and objects at high magnification. If the scanning of the electron beam is also coupled to detection of x-rays from the electron impact on the...

In contrast to the TEM, the scanning electron microscope (SEM) works somewhat like a TV cathode-ray tube. An electron gun is used to scan a surface with the help of deflection coils and focusing lenses in a raster pattern, and the reflected electron signal is used synchronously to generate an image of very high magnification on a screen. The SEM has been in...
