With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

Nearly a century ago, Ernst Ruska and Max Knoll provided the first demonstration of a microscope that could image specimens using electrons rather than light. The earliest images obtained via this ...

This instrument is an ultra-high-resolution scanning electron microscope capable of secondary-electron image resolution of 1.2 nm. It is fully digital and incorporates an image archiving computer.
