    Before the twentieth century, the microscopes as it was publicly known today came with the development of technology and improved optics. The microscope can view small microorganisms in micrometers. Microscopes are the equipment used to see the tiny microorganisms by enlarging the image and adjust it. ‘Micro' can be defined as small while' scope' is defined as to look at. The Microorganism is measured in micrometers and only microscopes are able to view microorganisms. Micrometer (µm) also called

    Implication What are microscopes? Microscope: first used in the 1650s, microscope is descended from the Modern Latin microsopium, meaning "an instrument for viewing what is small." In science, microscopes are essential for examining things that can't be seen with the naked eye. The microscopes have been invented a long time back because few scientists wanted to view and magnify images to see a better picture of it; they got this idea from water droplets.The main parts of a microscope are: • Eyepiece Lens:

    Definition of microscope; the microscope is an instrument which is used for magnifying objects that are too small to see with the naked eye; such as cells, bacterias and other microorganisms (particles). It gives an enlarged image of the object. Definition of lens; a piece of glass, or another transparent material, with curved sides. Used for bending light rays (concentrating or dispersing) which passes through. The phenomenon that causes the light to bend when crossing the lens is called refraction

    The English Scientist, Robert Hooke (1635-1703), was the first to publish work based upon the use of an optical microscope, in 1665. He was the first to use the word “cell” in the biological context. Hooke used a compound microscope, having two lenses, whereas Antoni Van Leeuwenhoek, a Dutch cloth merchant and Amateur Scientist, used only a single glass lens in his simple microscope, some 10 years or so later. Leeuwenhoek made observations on bacteria, plants, blood cells and minerals and

    makes use of a light source to illuminate the sample and uses lenses to magnify the image. This system is coupled with CCD and CMOS to get digital images. Light microscope has two basic divisions, simple microscope and compound microscope. Confocal microscopy and fluorescent microscopy, in addition to the techniques used by light microscope uses other techniques to extract image details. Optical Microscopy utilizes white light and the size range of the particle that could be viewed is limited to half

    A light microscope (LM) is an instrument that uses visible light and magnifying lenses to verify small objects that are not visible to the naked eyes or in finer detail than the naked eye allows. A light microscope uses two or more lenses to magnify the specimen and it have two sets of lenses which is stage and ocular (Bregman, 1983). Specimens are magnified by the objective lens which is magnified 100 times. The specimen is illuminated by visible light from the light source (the illuminator) that

    How does the microscope work? How does it use light? Optical microscope: a microscope that uses visible light in order to create images. The optical or light microscope consists of different parts (as you see in the picture), and each piece have a different name. The eyepiece lens consists of one lens, and that’s where you look through. The tube below the eyepiece lens connects it with the objective lenses (ultimate power of magnification). The eyepiece lens has a magnification of

    The optical microscope also known as a light microscope was first invented in the 17th century. Although there is some dispute on who was responsible for coming up with the optical microscope, it is widely believed that it was invented by a Dutch man named Antonie van Leeuwenhoek ( ). The optical microscope’s main function is to magnify small samples in order to improve resolution. The optical microscope was invented at a time when scientific research and discoveries were emerging and the scientific

    developments of the microscope, it consisted of a powerful convex lens and an adjustable holder for the object being studied. This instrument would have been able to magnify objects up to 400x and with it he discovered protozoa, spermatozoa, and bacteria, and was able to classify red blood cells by shape. The limitation with this microscope was the single convex lens. This was fixed by the addition of a second lens, giving rise to the compound microscope which is the basis of light microscopes today. During

    An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. Because the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, the electron microscope has a higher resolving power than a light microscope and can reveal the structure of smaller objects. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large

The science of examining small objects using such a tool is called microscopy. Microscopic means invisible to the eye except aided by a microscope. 2. HISTORY FIRST Zacharias Jansen (1580–1638) invented a compound light microscope and after that Antony van Leeuwenhoek in 1632–1723 invented a simple (one-lens) microscope that earned a lot of importance worldwide.

    INTRODUCTION OF LIGHT MICROSCOPE The light microscope is an instrument used for magnifying research specimens. Light microscopes are an invaluable analytical tool that has the potential to allow scientific investigators to view objects at 1000 times their original size. Light microscopes magnify and resolve the image of an object that is otherwise invisible to naked eye. Since its invention, the microscope has been a valuable tool in the development of scientific theory. Magnifying lenses have been

    Transmission Electron Microscope is a type of electron microscopy that forms detailed images called micrographs. (David B. Williams et al, 1996) states that the images form by passing a beam of electrons through a very thin slice of the area of interest. The transmission electron microscope operates on the same principles as the light microscope but uses electrons instead of light. What we see with a light microscope is limited by the wavelength of light. Transmission electron microscope use electrons as

    the use of a Scanning Electron Microscope (SEM) to examine and analyze metal samples that were subject to different failure tests. These failure tests included tensile tests, impact tests, and fatigue tests. SEM’s are useful because they provide a 3D view of the surface of the material, which improves the ability to examine the failure type at a microscopic level. In addition to this, the resolving power of a SEM is much stronger than that of a standard microscope, which enables the user to obtain

    Scanning tunneling microscopy: Scanning tunneling microscope is a device used to map to topography of a material at atomic level. It works by running a sharp tip which is only a single atom thick over the surface of material. The tip voltage is higher than material. This voltage allows tunneling current to flow from electrons that tunnel from the surface of material to tip of material through potential barrier. By measuring the amount of current the microscope can resolve where the atoms are on the surface

    Electron microscopes are scientific microscopes which utilizes a beam of accelerated electrons to get a detailed image of thin sections of a sample. There are two different types of the electron microscope, the first being a transmission electron microscope (TEM) and the scanning electron microscope (SEM). While both the scanning electron microscope and the transmission electron microscope work under the same concept, the SEM focuses on the samples surface and composition whilst the TEM will give
