The SEM is an instrument that produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun.

The thermionic electron gun can be set from 1-20kV. The SEM scans a beam of electrons over the specimen to produce a magnified image. The electrons from the beam hit the surface of the sample and ...

A pneumatic valve seals the gun ... image is from secondary electrons created when the beam is positioned at a point on the sample. This unique lens focuses the beam onto the sample and helps the ...

Improvements in resolution, depth of field, and electron detection technology have allowed SEMs to produce even more detailed and insightful images of specimens. Technological innovations such as ...

EBSD is commonly performed in a scanning electron microscope (SEM) equipped with a specialized EBSD detector. This illustration depicts the detection geometry commonly used in Electron Backscatter ...

Available with both SE and BSE detectors, the EM-30 allows the operator to view either detector individually, side-by-side, or as a composite image for a better understanding ... COXEM’s EM-30 series ...
