- 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.
- This is the part that holds two or more objective lenses and can be rotated to easily change power.
- Connects the eyepiece to the objective lenses
- The flat platform where you place your slides. Stage clips hold the slides in place.
- Allows you to direct ambient light up through the hole in the stage and illuminate the specimen.
5 True/False questions
Stage Clips → On a low power microscope, there is a frosted circular glass plate that fits in over the lower illuminator.
Stage Plate → Clips on the stage used to hold the slide in place.
Arm → The bottom of the microscope, used for support
Diaphragm → 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.
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.
