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 … Read more Types of Microscopes

Darkfield Microscope Definition Microbiology, the branch of science that has so vastly extended and expanded our knowledge of the living world, owes its existence to Antoni van Leeuwenhoek. In 1673, with the aid of a crude microscope consisting of a biconcave lens enclosed in two metal plates, Leeuwenhoek introduced the world to the existence of … Read more Darkfield Microscope- Definition, Principle and Uses
Phase contrast microscopy definition Unstained living cells absorb practically no light. Poor light absorption results in extremely small differences in the intensity distribution in the image. This makes the cells barely, or not at all, visible in a brightfield microscope. Phase-contrast microscopy is an optical microscopy technique that converts phase shifts in the light passing … Read more Phase contrast Microscopy- definition, principle, parts, uses
Fluorescence microscope definition A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation while phosphorescence is a specific type … Read more Fluorescence Microscopy- definition, principle, parts, uses
Compound Microscope Definition The term microscope can be split into two separate words, ‘micro’ and ‘scope’, where the term ‘micro’ means small or tiny, and ‘scope’ means to view or to observe. Therefore, a microscope can be understood as an instrument to observe tiny elements. The optical microscope often referred to as the light microscope, is a type of microscope that uses … Read more Compound microscope- definition, labeled diagram, parts, uses
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 … Read more Electron microscope- definition, principle, types, uses, images
The optical microscope often referred to as the light microscope, is a type of microscope that uses visible light and a system of lenses to magnify images of small subjects. There are two basic types of optical microscopes: Simple microscopes Compound microscopes. Simple Microscope Definition A simple microscope is one that uses a single lens … Read more Simple Microscope- Definition, Principle, Parts, Applications
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 … Read more 36 Differences between light and electron microscope
