1.yes
2.
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.
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.
Objective lenses: One of the most important parts of a compound microscope, as they are the lenses closest to the specimen.
A standard microscope has three, four, or five objective lenses that range in power from 4X to 100X. When focusing the microscope, be careful that the objective lens doesn
