Click on the buttons to move between slides. .. (Make sure you are in “Slide Show” mode). The aims of this course are:. ● . to explain how X-rays are generated in the electron microscope. Microscopy is the technical field using microscopes to view samples and objects that can not be seen without unaided eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron and scanning probe microscopy..

(SEM) Electron Microscopy (SEM) and TEM Scanning electron microscopy is used for inspecting topographies of specimens at very high magnifications using a piece of equipment called the scanning electr The theory of image formation in electron microscope s is very similar to image formation in light microscope s.
