Electron Microscope. . Electron microscopy (EM) . is an electron beam which is focused into a small probe across the surface of a specimen . . The first electromagnetic lens was developed in 1926 by . Hans Busch. .. . AIM : T THEORY: Microscope is the most commonly used piece of apparatus in the laboratory. It produces greatly enlarged images of minute objects.
