A scanning electron microscope, or SEM, is a powerful microscope that uses electrons to form an image. It allows for imaging of conductive samples at magnifications that cannot be achieved using traditional microscopes. Modern l...

Scanning electron microscopy, or SEM, is a powerful technique used in chemistry and material analysis that uses a scanned electron beam to analyze the surface structure and chemical composition of a sample.

Modern light microscopes are limited by the interaction of visible light waves with an object, called diffraction. The smallest resolv...
