At the heart of a scanning electron microscope is a high-energy electron source positioned above a series of condenser lenses and apertures which focus these electrons into a beam. The position of this beam is altered by sets of deflection or scanning coils before the final lens aperture. A sample is placed in the path of the electron beam which is continuously deflected into a raster scanning pattern by the deflection coils. Module 3- Basics of Scanning Electron Microscopy.

Keeping the tunneling current constant while scanning the tip over the surface, the tip height follows a contour of constant microscopy relates to the ordinary, classic microscope. The name derives from the fact that the entire field of view in the microscope is uniformly illuminated, and can be viewed through eyepieces or photographed using a camera. In confocal microscopy, on the other hand, a focused spot of light is scanned across the specimen to record an image.

Watch this video to see how a scanning elec Electron microscopes use a beam of electrons rather than photons of light to generate images from their subjects. The accelerating voltage of a scanning electron microscope is variable, usually in the range 500-30,000 volts. An electron accelerated by a potential of 30Kv has a shorter wavelength than one accelerated by a 5Kv potential.
