Read on to find out more about microscope parts and how to use them. The eyepiece contains the ocular lens, which the user looks through to see the magnified specimen.

Microscopy

The microscope that you will use is called a compound microscope. You will need to know the names of some of its component parts:. The eyepiece, or ocular, is located at the top of the main tube.

Microscope Parts & Specifications

Microscope , instrument that produces enlarged images of small objects, allowing the observer an exceedingly close view of minute structures at a scale convenient for examination and analysis. Although optical microscopes are the subject of this article, an image may also be enlarged by many other wave forms, including acoustic , X-ray , or electron beam , and be received by direct or digital imaging or by a combination of these methods. The microscope may provide a dynamic image as with conventional optical instruments or one that is static as with conventional scanning electron microscopes. A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye.

Historians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year more history here. The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope versus an electron microscope.
