A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.

The Sigma HD VP SEM, from Zeiss, is a variable pressure field emission scanning electron microscope. The instrument combines high resolution imaging with the capability to perform advanced analytics while maintaining flexibility and ease-of-use.

Scanning Electron Microscopes (SEM) scan a sample with a focused electron beam and obtain images with information about the samples’ topography and composition. CSEMs (conventional SEMs with a thermic electron source) and FE-SEMs (field emission SEMs with a field emission electron source) from ZEISS deliver high resolution imaging and ...
