    The causes of many of the illnesses that have plagued the human race have been found at the microscopic level. The microscope, one of the greatest human inventions, has helped find causes, and thereby treatments, for many of these illnesses. Moreover, the microscope can assist in solving crimes, as well as see the cells that make humans who they are. The origins of the microscope can be traced back to the Roman invention of glass in the first century A.D. When the Romans experimented with different

    Relevance: Microscopes are very important instruments that are used mainly in the fields of Science. The invention of the microscope allowed for the discovery of microorganisms, cells, elements of animals, fungi and plants that could not be seen by the naked eye. Microscopes have been used in forensics to solve crimes, to detect minerals, to determine how freezing/heating affects foods and to specify metals. Microscopes are also used in hospitals to diagnose infections and illnesses, and also to

    (micro means ‘small’ and scope means ‘to see’ = to see small things) A ‘light microscope’ uses two sets of lenses to make things seem much bigger than they really are… sometimes hundreds or thousands of times bigger. When things are made to look bigger than they are we say they have been MAGNIFIED. A ‘compound microscope’ magnifies things in two stages. Light from a mirror reflects up through the objects, which has to be very thin for the light to pass through. The light passes into a strong, powerful

    Microscope Research Paper The evolution of the microscope. The first form of the microscope was a crystal that was found by someone from a long time ago. The crystal was thick in the middle, but thinner around the egdes. The crystal made things look bigger when someone looked through it. The pearson also noticed that if the sun shone through the crystal, certain things could get burnt or set on fire. They were known as "magnifiers". Magnifiers were mentioned in the writings of the two Roman philosophers

In history, optical microscope is the first microscope to be developed containing one or more lenses producing an enlarged image of a sample placed in the focal plane by unidentified person. With the advancement of technology, compound microscopes that we are using today were claimed to be invented by Zacharias Jansen. Compound microscope is a microscope forming a magnified

    we had been able to learn the proper technique of using the optical microscope and preparation of different types of slides. Optical microscope, often referred to as light microscope, is a type of microscope which uses visible light and a system of lenses (4X, 10X, 40X and 100X) to magnify images of small samples. Image from an optical microscope can be captured by normal light-sensitive cameras to generate a micrograph. Microscope is one of the best technology provide information such as the staining

The earliest development of the microscope can be traced back to the ancient world with the appearance of the magnifying glass, which was at that time use as a “burning glass.”The conception of the action of the magnifying glass with regards to the production of a magnified image that could supplement the human eye first appeared in the 13th century. It was at this time that the ancestor of the microscope ancestor, the glass lens, first appeared

    Microscope Types The most widely used microscopes are optical microscopes, which use visible light to create a magnified image of an object. The simplest form of optical microscope is the double-convex lens with a short focal length. These lenses can magnify an object by up to 15 times. In general, however, a compound microscope is used, which has multiple lenses to provide more magnification than

    Light Microscopes Introduction Nobody in the entire world is capable of seeing microscopic things with a naked eye. For years, this has been a huge problem against humanity; people have died of diseases that scientists could not deal with or know about because they lacked of having the correct technology. Back then in the 1400s, they were not aware of bacteria, as microscopes were not invented during those days. They could only see the effect that the bacteria created, but still could not find

The invention & evolution of the microscope has been an ongoing process since the Middle Ages, when the first convex magnifying lenses were introduced. In 1590, the Jansen Brothers invented the first compound microscope (two or more lenses).However, Antony van Leevenwenhoek created the first “true” microscope, in 1665, with 300x magnification & unbelievable resolution. During the late 1700’s, the microscope was reinvented with 1500x magnification

    The earliest microscope magnified the object ten times the actual size. They were made up of a tube with a plate for the object at one end and, at the other, a lens which magnified the object. In 1609, Galileo worked with the lenses and made more advanced instrument with a focusing device. Anton van Leeuwenhoek taught himself methods of  polishing tiny lenses of extreme curvature which gave best magnification of that time up to 270 diameters. This led to the building of his microscopes and his discoveries

    crime laboratories depended merely on the microscope to study the structure and composition of matter. In the early 1950s, the scanning electron microscope (SEM) was developed and it added a new element to forensic science, which was previously unattainable within the restrictions of the ordinary light microscope. All other traditional microscopes use light coming off the specimen to produce a magnified image (Saferstein, 2011). The SEM is a special microscope in the sense that it uses electrons instead
