1. When you turn the high power objective into place, it is important to remember that it is retractable. When you hit the slide, the end of the lens will push in. This protects the slide and the lens. High power objective allows you to see a close up of a small area of the specimen being viewed.
2. Coarse adjustment is used to focus the microscope and has to be used only with low power objective.
3. Diaphragm or Iris has different sized holes and is used to change the intensity and size of the cone of light that is being projected upward into the slide. There is no such set conditions regarding which setting to use for particular power.
4. While handling microscope slides-
-Handle the slides at the ends and not at the center. This is to avoid getting fingerprints all over the slide.
-Never view a slide without a coverslip. The coverslip protects the lens from the liquid present on the slide.
5. Stage clips hold the slide in place.
6. During the viewing through the microscope, both eyes should be open. This prevents eye fatigue which may occur when the non-viewing eye is closed. Also, your eye should never touch the ocular lens. Remove eye glasses while viewing else it may touch the microscope and get scratched.
7. The arm and base are used to carry the microscope.
8. Coverslip protects the objective lens from the liquid present on the slide.
9. Lowest power objective lens is used to locate the specimen and for the first focus. Coarse adjustment is done with low power objective.
10. The chemicals that are sometimes used to make specimens visible are known as stains or staining reagents. Example-Methylene Blue and crystal violet.
11. If a high power objective lens touches or breaks the coverslip immediately inform the professor or teacher. Do not touch the broken glass.
