Electron microscopy is an effective method for examining the atomic and molecular structure and characteristics of materials. It includes the creation of high-resolution image of the sample under study using a concentrated beam of electrons. It uses electron optics that are analogous to the glass lenses of an optical light microscope to control the electron beam, for instance focusing it to produce magnified images or electron diffraction patterns. Let us make an in-depth study of the electron microscope . After reading this article you will learn about: 1. Principle of Electron Microscope 2. Transmission Electron Microscope (Tem) 3. Components of Electron Microscope 4. Preparation of Specimen 5. Image Viewing, Development and Recording Techniques 6. Use of Electron Microscope 7. High Voltage Modern Electron Microscope 8. Scanning Electron Microscope and 9. Phase Contrast Microscope . Introduction to Electron Microscope : In electron ... What is EM ? What is Electron Microscopy ? Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. The high resolution of EM images results from the use of electrons (which have very short wavelengths) as the source of illuminating radiation. Electron microscopy is used in conjunction with a variety ...
