3 MagnificationTotal magnification is achieved by multiplying the power of the ocular lens by the power of the objective lensTotal Magnification = Ocular Lens X Objective Lens
4 Objective Lens Red Band = Low Power = 4 4(obj lens) X 10(ocular lens) = 40XYellow Band = Medium Power = 1010(obj lens) X 10(ocular lens) = 100XBlue Band = High Power = 10040(obj lens) X 10(ocular lens) = 400XWhite Band = Oil Immersion
5 Follow the Rules! ALWAYS begin on LOW POWER Once you have the specimen in focusMove to medium powerRefocus, then you can move to high powerOnce you move off low power, you can NEVER, NEVER, NEVER use the coarse adjustment
