Oct 27, 2024 · Structural parts of a microscope and their functions. There are three structural parts of the microscope i.e. head, arm, and base. Head – The head is a cylindrical metallic tube that holds the eyepiece lens at one end and connects to the nose piece at other end. It is also called a body tube or eyepiece tube.
- 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.
