Parts of the microscope

Ocular lens also known as the eyepiece; the lens at the top that you look through; typically 10X or 15X power
Body tube Connects the eyepiece to the objective lenses
Arm Supports the tube and connects it to the base; used along with the base to carry the microscope
Base The bottom of the microscope; used for support
Illuminator also known as the light source; can be a mirror or plug-in light source; provides light to see the specimen
Stage The flat platform where you place your slides
Stage clips Holds the slide in place on the stage
Revolving nosepiece Also known as the turret; holds two or more objective lenses and can be rotated to easily change power
Objective lenses shortest lens is the lowest power; longest lens has the greatest power; these lenses are multiplied with the ocular lens to get a total magnification (scanning lens - 4X, Low Power - 10X, High Power - 40X)
Diaphragm also knows as the iris; found under the stage and contains various sized holes to control the amount of light on the specimen
Coarse adjustment Use to focus the microscope; always used first and should start at the lowest position without touching the slide
Fine adjustment Lets you fine-tune the focus
