Types of Microscopes

A good microscope should have three properties: Good resolution: Resolution power refers to the ability to produce separate images of closely placed objects so that they can be distinguished as two separate entities. The resolution power of: The unaided human eye is about 0.2 mm (200 μm) The light microscope is about 0.2 μm An electron microscope is about 0.5 …

Electron Microscope

Electron microscope definition An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. It is a special type of microscope having a high resolution of images, able to magnify objects in nanometres, which are formed by controlled use of electrons in vacuum captured on a phosphorescent screen. Ernst Ruska (1906-1988), a German engineer and academic professor, …

36 Differences between light and electron microscope

Differences between Light and Electron Microscope

Both light microscopes and electron microscopes use radiation (light or electron beams) to form larger and more detailed images of objects which cannot be seen clearly through an unaided eye. However, each of these microscopes has distinct features and is suitable for different purposes. S.N. Character Light Microscope Electron Microscope 1.       Alternatively known as Optical microscope Beam microscope 2.       Invented …
