Microscope, an instrument that typically uses one or more lenses to produce enlarged images of small objects, especially of objects too small to be seen by the naked eye.  By far the most widely used microscopes in schools, science, medicine, and industry are the various types of light microscopes, the subjects of this article.  Light microscopes, the subjects of this article.  Light microscopes can provide useful magnifications as high as 2500x.  Electron microscopes are special-purpose field-emission microscopes, which do not use lenses, yield magnifications up to several thousand times higher than this.

The instrument normally brought to mind by the word microscope is a compound microscope of the type commonly used by biologists, doctors and medical researchers.  In its simplest form, as made in the 17th century, it consisted of two optical elements - the objective lens, located close to the object under study, and, at some distance from the objective (usually about 150mm), a second lens, which served as the eyepiece.  Many of today's microscopes are of the same basic construction except that the objective and eyepiece components are not single simple lenses but are each made of tow or more optical elements.

Stereoscopic microscopes give the viewer an erect (right side up) three-dimensional image of the specimen.  They are essentially two microscope optical systems built into one mechanical unit.  Such microscopes are of necessity binocular, with each side of the system seeing the specimen from a different perspective.  Stereoscopic microscopes are widely used in biological laboratories for dissecting tiny biological specimens and in industry for assembling and inspecting small parts.
