Electron Microscopy

Electron microscope are the magnifying instruments that utilizes the beam of high speed electrons to illuminate the object. Electron microscopy was discovered for visualizing the ultra-structure of the microorganisms, cells etc. It gives high magnification (up to 1000000x) and incredibly high resolution (dependent upon the wavelength of radiations).

Microscope and Microscopy

Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye. It is a simple, direct technique for examining the morphology of cells and their organelles.
A microscope is an instrument that magnifies objects otherwise too small to be seen, producing an image in which the object appears larger.
Depending upon the principle on which magnification is based, microscopes are of two categories: Light and Electron.
