Electrostatic lens. An electrostatic lens is a device that assists in the transport of charged particles.[1][2][3] For instance, it can guide electrons emitted from a sample to an electron analyzer, analogous to the way an optical lens assists in the transport of light in an optical instrument.
Electromagnetism is the effect of the electromagnetic force, which is one of the four fundamental forces in the universe.lectromagnetism is the force that causes the interaction between electrically charged particles, and is responsible for practically all the phenomena observed in daily life, except gravity. Electricity and magnetism are the two obvious examples. The chemical bonds holding molecules together are electromagnetic.
