•Parts•Microscope Usage

The microscope makes things look larger. It works by gathering light from a light source. The light source can be either a small light bulb or a mirror reflecting light from an outside source. Light passes through the specimen and then through the lenses. Each lens is a piece of glass that has been shaped in a curve so that the light bends, magnifying the specimen.

The ocular, or eyepieceThe ocular, or eyepiece, is the lens you look through in a microscope. It usually has a magnification of 10X. Every microscope has an eyepiece.

Body TubeBody Tube::  Connects the eyepiece to the objective lenses

The stage clips The stage clips keep the slides from slipping off the stage. The stage is where you set the slide down to view. The slide is what you put your specimen in that you want to view.

Generally, three or four objective lenses are found on a microscope, with ranges of 10X, 40X, 100X powers. Lenses are colour coded, the shortest lens is of the lowest power, and the longest lens is high power lenses.

Fine adjustment knob: Fine adjustment knob: Used for focus on oil. Moves the body tube for focussing the high power lens.

Coarse adjustment knob: Coarse adjustment knob: Used for focus on scanning. Usually the low power lens is used enabling the movement of the tube.

BaseBase::  The bottom of the microscope, used for support

The illuminator, or light source, The illuminator, or light source, is located under the stage of a microscope. It is either made of mirrors or an electric light. The object of the light is to give you a bright background so you can more easily see the object on the slide.

The Stage The Stage is the flat platform where you place your slides.

DiaphragmDiaphragm helps in controlling the amount of light that is passing through the opening of the stage. It is helpful in the adjustment of the control of light that enters

NosepieceNosepiece is also known as the TurretTurret. Resolving nosepiece holds two or more objective lenses and can be rotated to easily change power

ApertureAperture is the hole in the stage through wich the base light reaches the stage

Arm:  Supports the tube and connects it to the base
