PPT-An Introduction to Electron Microscopy

Because these electron micrograph EM images are very detailed you should view this demonstration in the Slide Show view Click the Slide Show tab then select From Beginning or for the true geek the little projector icon in the lower right After that your updown arrows will advance or retreat the demonstration.

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..

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. .. . (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 Theoretically a microscope is an array of two lenses Need of M icroscopy Living organisms, cells and their organelles which are too small to be seen with the human eye, can only be seen with the aid The theory of image formation in electron microscope s is very similar to image formation in light microscope s. However, the practice and design are completely different : The most crucial 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.
