Light Microscope (LM):

A light Microscope works by passing visible light through a specimen.

Structure of Light Microscope:

It uses two glass lenses. One lens produces an enlarged image of the specimen and the second lens magnifies the image and projects it into the viewer's eye or onto photographic film.

Micrograph:

A photograph taken through a microscope is called a Micrograph.

Function Of light Microscope:

The LM cannot resolve(distinguish) objects smaller than 0.2µm. It is about the size of the smallest bacteria. The image of a Bacterium can be magnified many times, but the Light Microscope cannot show the details of its internal structure.
