    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
