- 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.
- This is the rough focus knob on the microscope. You use it to move the objective lenses toward or away from the specimen.
- This is the knob used to fine tune the focus on the specimen. It is also used to focus on various parts of the specimen. Generally one uses the coarse focus first to get close then moves to the fine focus knob for fine tuning.

Stage Clips → On a low power microscope, there is a frosted circular glass plate that fits in over the lower illuminator.
Turret → This is the part that holds two or more objective lenses and can be rotated to easily change power.
Oil Immersion Lens → 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.
