electron lens
1. Electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons.
2. An electric or magnetic field, or a combination of such, that acts upon an electron beam in a manner similar to that in which an optical lens acts upon a light beam.
3. A tool which uses an electromagnetic field to refract an electron beam in a manner similar to the refraction of light by an optical lens.
4. A system of deflecting electrodes or coils designed to produce an electric field which influences a beam of electrons in the same manner that a lens affects a light beam.
5. An electric field used to focus a stream of electrons on a target.
