An electron source—also referred to as an electron gun—emits electrons that get accelerated by an applied voltage. Magnetic lenses converge the stream of electrons into a focused beam, which then hits the sample surface in a fine, precise spot. The electron beam then scans the surface of the specimen in a rectangular raster.
