Quick Discription
A microscope is an instrument for viewing objects that are too small to be seen by the naked eye.
A number of professions in the fields of biology, chemistry, zoology, criminal justice, medicine and more use microscopes on a daily basis.
There are three main types of microscopes
1.The Light Compound Microscope
This is the most common microscope for school science classes and of any scientist, it is readily available and is also extremely easy to operate and has the advantage of being able to look at live small cells. The microscope uses light from a tiny area of a thin, well-illuminated specimen that is close-by and the objective lens zooms in on the specimen to look on the level of cells and sometimes further defending on the lens.

2.Scanning Electron Microscope
Scanning electron microscope uses a beam of electrons to scan an object magnifying the image many times more than a light microscope. It requires some specialised equipment to prepare the specimens for observation but has the advantage of observing large specimens. But it is very expensive and require special training to operate and prepare.

3.Transmission Electron Microscope
The Transmission Electron Microscope uses a beam of electrons to form an image of a specimen thousands of time higher magnification than either the light compound microscope and scanning electron microscope. It has to have very thin, killed, fixed and stained specimens. But the instrument is very expensive, need specialised equipment, extensive training, and specialised facilities.
