Eye Piece (ocular) Coarse Focus Body Tube Fine Focus Revolving Nose Piece Arm Low Power Objective Stage Clips High Power Objective Stage Pivot Point Diaphragm Base Mirror
2
1) Eye Piece (ocular) – 2) Body Tube – the lens that you look through
the tube that supports the eyepiece
3
3) Revolving Nosepiece-
the rotating device that holds and changes the objectives (lenses). Revolving Aperature- Opening in the stabe to allow light from mirror or light to pass
4
5) High Power Objective –
4) Low Power Objective – magnification lens with the lowest power 5) High Power Objective – magnification lens with the highest power 6) Stage Clips – clips that keep the slide or specimen from moving on the stage
5
7) Stage – holds the specimen
6
8) Diaphragm- controls the amount of light entering through the aperature to the objectivefrom the bottom
7
9) Pivot Point- 10) Base- 11) Mirror
part that allows you to tip the ocular toward you Pivot Point Base Mirror 10) Base- supports the microscope 11) Mirror reflects (bends) the light upward onto the slide
8
12) Fine Focus Adjustment –
moves the body tube in small increments 13) Coarse Focus Adjustment- moves the body tube in large increments 14) Arm – attaches the eyepiece and the body tube to the base

Magnification A how to guide...
10
Calculate Total Magnification
ocular power x objective lens power using Ocular power is generally 10X, meaning it has a magnification or power of 10X
11
MULTIPLY
12
Magnification Elodea 40 x Elodea 100x Elodea 400x
