Electron microscopes use a focused beam of electrons instead of light to "image" the specimen and gain information as to its structure and composition. Common types of information yielded are ...

Scanning electron microscopy is a general type of electron microscopy that generates a topological image of a sample using a beam of electrons to achieve much higher spatial resolution than light ...

Metallurgical microscopes can be one of many types of technologies. The most common metallurgical microscopes are acoustic ... portable field microscopes, scanning electron (SEM) microscopes, scanning ...

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher ...

The scanning electron microscope is a type of electron microscope that produces images of a sample by scanning it with a high-energy beam of electrons. The SEM is significantly more powerful than ...

Science presenter Jon Chase describes three different types of microscope ... the difference between a transmission and scanning electron microscope and views some images of cells, organelles ...
