The lens in an electron microscope focuses and magnifies the electron beam to produce high-resolution images of tiny objects.
An electron gun is a device that emits a focused beam of electrons. It is commonly used in cathode ray tubes (CRT) in TVs and computer monitors to generate images by directing the electron beam onto a phosphor-coated screen, causing it to light up and produce images.

Electron beam welding works by using a high-velocity beam of electrons to heat and melt metal surfaces, creating a strong bond when the metal cools. The key principles of electron beam welding include focusing the electron beam with magnetic fields, controlling the beam's power and speed, and using a vacuum chamber to prevent interference from air molecules.
An electron microscope does not use a beam of light. Instead, it uses a beam of electrons to visualize specimens at much higher resolution than can be achieved with light microscopes.
The size of a laser or electron beam is measured in milliradians. This is because they are subject to divergence.

four coils are used to create a magnetic field to deflect the electron beam in two dimensions.

Actually, electron microscopes use a beam of electrons instead of light to produce a magnified image. This allows for much higher magnification and resolution compared to optical microscopes.
