ELECTRON MICROSCOPE
The fact that energetic microscopic particles have extremely short Debroglie wavelengths has been put to partical use in many ultra-modern devices of immense importance such as an electron microscope.


Electron microscope makes parttical use of the wave nature of the electrons which is thousand of time shorter than visible light which enables the electron microscope distinguish details not visible with optical microscope. In an electron microscope, electric and magnetic fields rather than optical lenses are used to focus electrons by means of electromagnetic forces that are exerted on moving charges.The objective and the intermediate lenses produce a real intermediate image and projection lens from the final image, which can be viewed on a fluorescent screen or photographed on special film known as electron micro-graph. A three dimensional image of remarkable quality can be achieved by modern version called scanning electron microscope.
