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. .. . Figure 1:Field emitter gun; the electron source in field emission scanning electron microscope. The only electron source designed for highresolution imaging and suitable for various kinds of materials The aims of this course are:. ● . to introduce the principles of scanning electron microscopy. ● . to describe the components of the microscope and explain how they work. ● . to highlight some of the problems which can arise during imaging.

It is a scientific equipment . that . magnifies . very small . objects that is not visible to the naked eye to an extent where it can be seen clearly.. The Eyelid. The eyelid protects the front part of the eye. . The lid helps keep the eye clean and moist by opening and shutting several times a minute. . Blinking. - both a voluntary and involuntary action, meaning you can blink whenever you want to, but it also happens without you even thinking about it..
