Introduction:

Microscope is an instrument used to see objects that are not visible from the naked eyes. It was first used by scientist of Renaissance. There are three important parameters in microscopy which are magnification, resolution and contrast. Magnification is the enlargement of the object size. It is the ratio of object size to the real size. The clarity of the image is the measure of the resolution of the microscope whereas difference in the brightness of dark and light areas of the object is known as contrast parameter of the microscope.
