Summary Introduction
Introduction:
A microscope is an optical instrument used to view the objects that cannot be seen with the naked eye. It is constructed with a combination of lenses to get the enlarged vision of the object. The microscopes are classified into different types in order to view the different types of specimens. Each microscope produce a different kind of images.
