How Does a Microscope Work?

The simplest kind of microscope is a hand-held magnifying glass. The glass, which is ground into a curved shape, bends rays of light passing through it, producing a larger image than the original.

A compound microscope has two or more curved lenses in a tube. The object to be studied is placed on glass so that light from underneath passes through it. The first lens enlarges the image, which is then magnified by the other lenses.

When looking through a microscope, objects may appear 10 to 2,000 times their size. The invention of the optical microscope transformed the field of science because it allowed people to examine the world in microscopic detail.

All microscopes are basically carrying out three functions: Magnify an object with the help of lenses. Light up the specimen (object) being examined. Allow you to focus and make the details of this object visible.
