Uses

• Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens
• Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.
• Body tube (Head): The body tube connects the eyepiece to the objective lenses.
• Arm: The arm connects the body tube to the base of the microscope.
• Coarse adjustment: Brings the specimen into general focus. see
• Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
• Nosepiece: A rotating turret that houses the objective lenses. The viewer spins the nosepiece to select different objective lenses.
