Title: Microscopy – Scientific Application and 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: the lens at the top that you look through.
• Tube: Connects the eyepiece to the objective lenses
• Arm: Supports the tube and connects it to the base
• Base: The bottom of the microscope. …show more content…
If your microscope has a mirror, it is used to reflect light from an external light source to see the specimen clearly
• Stage: The flat platform where you place your slides. Stage clips hold the slides with the specimen in place. If your microscope has a mechanical stage, you will be able to move the slide around by turning two knobs.
• Revolving Nosepiece or Turret: This is the part that holds two or more objective lenses.
• Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4X, 10X, 40X and 100X powers.
• Condenser Lens: condenser lens is used to focus the light onto the specimen.
• Diaphragm or Iris: Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide.
Applications and implications of the microscopy on different fields in medicine
Depending on specific problem if field of medicine and scientific implications, that need to be evaluated and discussed, application and type of microscope can be selected, such as;

Extremely detail study that focuses solely on the anatomical changes that occur in diseased tissue at a microscopic level. Histopathology Electron Microscope-The electron microscope (EM) is one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These wavelength strike objects that come in its path and helps increase the resolution of the microscope. It is used to study tiny viral cells as well as larger molecules.
Spread awareness through digital media about all kinds of different viruses or infected cells. Digital Pathology extends the limits of microscopy, enabling, educators, researchers, and clinicians to share tissue samples. Images sent or shared over the Internet. Digital pathology : Digital microscope -Uses optical lenses as well as CCD/CMOS sensors. It provides a 1000x magnification power. It is used to get high quality recorded images of the specimen.

Tumors (a lot of infected cells together). Deeper study to observe and analyze infected and infectious cells.

two objects, the higher the resolution the greater the detail. Electron microscopes have some advantages over optical microscopes: The biggest advantage is that they have a higher resolution and therefore also have a higher magnification (Up to 2000000 times). Light microscopes can only show a useful magnification only up to 1000-2000 times. This is a physical limit imposed by the wavelength of the light. Electron microscopes therefore allow for the visualisation of structures that would normally…

Transmission Electron Microscope Introduction For analysis of materials of very small dimensions like quantum dots, quantum wires, nano tubes, nano dots, fullerenes etc. we need special kind of microscopes. As photons of light have wavelengths larger than that of most of the nanomaterials, optical microscopes doesn’t have magnification power or resolution capabilities to cater these materials. For this purpose electron microscopes, which uses electrons having shorter wavelengths, like Transmission…

Microscopes A microscope is a tool scientist use to see living or non-living things that cannot be seen by the naked eye. There are two main types of microscopes. They are light microscopes and electrons microscopes. Light microscopes produce magnified images by focusing visible light rays. Compound light microscopes allow light to pass through using two lenses to form an image. Electron microscopes produce magnified images by producing beams of electrons. Biologist uses two main types…
