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

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.
