- A rotating disk under the stage that is used to vary the intensity and size of the cone of light that is projected upward into the slide.
- They almost always consist of 4X, 10X, 40X and 100X powers. When coupled with a 10X (most common) eyepiece lens, we get total magnifications of 40X (4X times 10X), 100X , 400X and 1000X.
- Allows you to direct ambient light up through the hole in the stage and illuminate the specimen.
- an objective lens (usually 100X or greater) designed to work with a drop of special oil placed between it and the slide. With oil, an increase in resolution will be noticed.
- The bottom of the microscope, used for support
