Description
An electromagnetic or electrostatic field used to focus and deflect the electron beam through the optical column in an electron microscope. An electromagnet consists of a coil of wire wrapped around a soft iron core that is magnetized only when current flows through the wire. An electrostatic lens is a metal plate that can be positively or negatively charged to attract or repel the beam.
