__ Poster- types of microscopes __

There are two types of microscopes for looking at cells, light microscopes and electron microscopes.

Compound microscopes: In 1590 the first compound microscope was invented by two Dutch spectacle makers, Zaccharias Janssen and his son, Hans Janssen. In 1609, Galileo, heard of these early experiments, and made a much better instrument with a focusing device this device was called a microscope.

The compound microscope allows the detailed study of micro-organisms, cells and tissues. These types of microscopes are therefore widely used in scientific and medical research

Stereo or dissecting microscope: A dissecting microscope is a microscope of a design which facilitates the magnification and examination of three dimensional objects, rather than samples prepared on slides. As the name implies, dissecting microscopes are commonly used in the dissection of specimens, but they have a range of other functions as well.

Light microscope: Light microscopes are good for looking at small objects, and are probably the most well-known and well-used research tool in biology. The light helps you detect small things you can’t see.
