scanning electron microscope
Scanning Electron Microscope (SEM)
Charles Oatley in 1952 discovered the electron scanning microscope, but Max Knott created the first prototype of the SEM in 1935.
It uses electromagnets.
It uses a combination of lenses.
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.

I and II. Compound and dissecting microscopes can be used to view living samples due to their lower magnification and non-destructive imaging techniques. III and IV. Scanning and transmission electron microscopes are not ideal for viewing living samples as they typically require a vacuum environment and can damage the specimens.
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.
Stereomicroscope, Compound Microscope, Phase-contrast microscope, electron microscope, Scanning-electron microscope, Transmission electron microscope, Confocal-scanning microscope. THESE ARE JUST SOME. :)

The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.
The abbreviation "SEM" stands for scanning electron microscope.SEM is a type of microscope that uses electrons to create high-resolution images of a sample's surface topography and composition.
