microscope

A device that produces a magnified image of objects too small to be seen with the naked eye. Such objects are thus called “microscopic.” The microscope is widely used in medicine and biology. Common microscopes use lenses; others, such as electron microscopes, scan an object with electrons, x-rays, and other radiation besides ordinary visible light.
