The magnification of a compound light microscope can go up to about 1,000×. This magnifying power makes it possible to study tiny living things such as bacteria, algae, protozoans, and many types of cells.

Microscopes definitionand examples

The size of an image depends on the lenses used. For example, an objective lens might make an object appear 10 times larger than it really is. This lens is said to have a magnification of 10×. If the eyepiece also has a magnification of 10×, the total magnification of the microscope is 10 times 10, or 100×.

Types of microscope

A special type of optical microscope is a compound microscope. In a compound microscope a lens near the object makes a larger image (picture) of the object. This lens is called an objective lens. Another lens, known as the eyepiece, bends the light again. As a result, the eyepiece forms an even bigger image of the image made by the objective lens.

Principle of microscope

There are several types of microscopes. Optical microscopes, also called light microscopes, work like magnifying glasses. They use lenses, which are curved pieces of glass or plastic that bend light. The object to be studied sits under a lens. As light passes from the object through the lens, the lens makes the object look bigger.

To view small objects even more closely, scientists use electron microscopes. These microscopes use beams of electrons instead of light to magnify objects. Electrons are some of the particles, or bits, that make up atoms. Electron beams cannot travel far in air. Objects must be put in a vacuum, or airless space, before they can be seen with an electron microscope.

A microscope is a device that magnifies tiny objects, or makes them look larger. People use microscopes to see objects that are too small to be seen with the eye alone. Such objects include cells, tiny living things, and grains of sand.

Electron microscopes can magnify objects up to 1 million times. This magnifying power makes electron microscopes very important scientific tools. However, they cannot be used to study living things because living things cannot survive in a vacuum.
