2. Introduction to the Microscope  Care  Parts  Focusing

3. Always carry with 2 hands Only use lens paper for cleaning Do not force knobs Always store covered Keep objects clear of desk and cords

4. Eyepiece Body Tube Revolving Nosepiece Arm Objective Lens Stage Stage Clips Coarse Focus Fine Focus Base Diaphragm Light

5. Place the Slide on the Microscope Use Stage Clips Click Nosepiece to the scanning power(shortest) setting Look into the Eyepiece Use the Coarse Focus

6. Follow steps to focus using low power Click the nosepiece to the longest objective Do NOT use the Coarse Focusing Knob Use the Fine Focus Knob to bring the slide into focus. What can you find on your slide?

7. Magnification Most microscopes have three magnifications 1.Scanning Power-Shortest setting 2.Low Power-Middle Setting 3.High Power-Longest Setting ***

8. Magnification The eyepiece or ocular lens has a magnification of 10. Total Magnification is the objective lens x ocular lens.
