After exiting the gun, the beam passes through an electromagnetic lens and deflection coil system.
2.
The electrons are then accelerated by an electric potential ( measured in volts ) and focused by electrostatic and electromagnetic lenses onto the sample.
3.
He also helped to advance the field of electron cryomicroscopy-the use of superconductive electromagnetic lenses cooled with liquid helium in electron microscopes to achieve the highest resolution possible-among many other research topics.
4.
An ESEM employs a scanned electron beam and electromagnetic lenses to focus and direct the beam on the specimen surface in an identical way as a conventional SEM . A very small focused electron spot ( probe ) is scanned in a raster form over a small specimen area.
