    1. 1. Eye Piece (ocular) Coarse Focus Fine Focus Arm Stage Clips Pivot Point Base Body Tube Revolving Nose Piece Low Power Objective High Power Objective Stage Diaphragm Mirror 1
    2. 2. 1) Eye Piece (ocular) – the lens that you look through 2) Body Tube – the tube that supports the eyepiece 2
    3. 3. 3) Revolving Nosepiecethe rotating device that holds and changes the objectives (lenses). Revolving AperatureOpening in the stabe to allow light from mirror or light to pass 3
    4. 4. 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 4 on the stage
    5. 5. 7) Stage – holds the specimen 5
    6. 6. 8) Diaphragmcontrols the amount of light entering through the aperature to the objectivefrom the bottom 6
    7. 7. 9) Pivot Pointpart that allows you to tip the ocular toward you Pivot Point Base Mirror 10) Basesupports the microscope 11) Mirror reflects (bends) the light upward onto the slide 7
    8. 8. 12) Fine Focus Adjustment – moves the body tube in small increments 13) Coarse Focus Adjustmentmoves the body tube in large increments 14) Arm – attaches the eyepiece and the body tube to the base 8
    9. 9. 9
    10. 10. Calculate Total Magnification Total Magnification = ocular power x objective lens power using Ocular power is generally 10X, meaning it has a magnification or power of 10X 10
