Microscope

A microscope is a scientific instrument used to view small objects. They are usually used to see details that are too small or not visible with the naked eye.

Light Compound Microscope
The light compound microscope is one of the most common types of microscopes.

Parts of a Light Compound Microscope

 * Ocular: This part of a microscope magnifies the image formed by the objectives. It is the part where the viewer looks through to see the image.
 * Nosepiece: Holds the objectives and is located below the arm and the body tube.
 * Base: Supports the microscope and acts as a foundation.
 * Objectives: Lenses that form the first image (before the ocular) by receiving light from the field of view.
 * Arm: Connects to the base and holds up the ocular, body tube, objectives, and nosepiece.
 * Body Tube: The tube between the ocular and the nosepiece/objectives.
 * Coarse adjustment: Used to adjust the microscope in lower power.
 * Fine adjustment: Used to adjust the microscope in high power or for fine tuning.
 * Stage: Supports the slide and specimen when being viewed.
 * Stage clips: Clips on the stage that hold the slide in place.
 * Illuminator: A source of light, usually located below the stage. A lumarod (rod that collects light) is sometimes used as a source of light in microscopes that do not use electric power.
 * Diaphragm: Controls the amount of light reaching the specimen.
