microscope is a scientific instrument. It makes small objects look larger. This lets people see the small things. People who use microscopes commonly in their jobs include doctors and scientists. Students in science classes such as biology or chemistry also use microscopes to study small things.
The earliest microscopes had only one lens and are called simple microscopes. Compound microscopes have at least two lenses. In a compound microscope, the lens closer to the eye is called the eyepiece. The lens at the other end is called the objective. The lenses multiply up, so a 10x eyepiece and a 40x objective together give 400 x magnifications.
Microscopes make things seem larger than they are, to about 1000 times larger. This is much stronger than a magnifying glass which works as a simple microscope.
Types of microscopes
The most common kind of microscope is the compound light microscope. In a compound light microscope, the object is illuminated: light is thrown on it. The user looks at the image formed by the object. Light passes through two lenses and makes the image bigger.
