- The eyepiece or ocular (1)
- The part of a microscope that a user looks into. It contains a lens called the ocular.
- Objective (3)
- The objective is another lens. It is located near the specimen to be observed.
- Body Tube
- This is a hollow tube that connects the ocular lens to the objective lens.
- Nosepiece (2)
- The nosepiece is the part of the microscope that the objective lenses attach to. Sometimes the nosepiece houses a prism whose function is to bend light from the image so that the user can sit comfortably instead of hunching over the microscope to look straight down on the specimen.
- Stage (6)
- The stage is a platform where the slides are mounted.
- Diaphragm (8)
- The diaphragm is an apparatus located beneath the stage. It focuses light onto the specimen.
- Base
- The base is the bottom of the microscope on which the rest of the instrument rests.
- Focus knob (4 and 5)
- The focus knob (or knobs) adjust the distance between the ocular lens and the objective lens. This brings the specimen into focus. Microscopes often come with two focus knobs - a coarse focus and a fine focus. The coarse focus knob makes large changes in the focus. The fine focus know makes smaller adjustments.
- Arm
- The arm connects to the base and other parts of the microscope (such as the stage, diaphragm, and body tube) attach to it.
