A scanning electron microscope (SEM) is a type of electron microscope that produces high-resolution images of a sample's surface by scanning it with a focused beam of electrons. The electrons interact with the atoms in the sample, generating signals that provide information about the surface topography and composition. SEM is widely used in various fields, including materials science, Biology, and Nanotechnology, due to its ability to achieve magnifications of up to 1 million times and its depth of field, which allows for detailed 3D imaging. Additionally, SEM can analyze samples in different environments, such as vacuum or controlled atmospheres.
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.

The most powerful microscope is currently the electron microscope, specifically the transmission electron microscope (TEM) and scanning electron microscope (SEM). These microscopes use beams of electrons to achieve magnifications up to millions of times, allowing for incredibly detailed imaging of samples at the atomic level.
Two types of microscopes that view the surface of an object are stereo microscopes, which provide a three-dimensional view, and scanning electron microscopes (SEM), which provide high-resolution images by scanning the surface with a focused beam of electrons.
Electron scanning microscopes scan metal deposited on surfaces.

A SEM microscope is a scanning electron microscope
The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
