How to Use a Microscope


1. Carry the microscope to your work area by the arm and the base.

2. Plug the microscope in and press the power switch. Check to make sure the lamp turns on. If it does not notify your teacher.

3. Turn the nosepiece until the scanning lens (smallest should have a 4 on it) is in place. A lens is in place when it is pointed directly at the stage.

4. Place your slide on the stage. Turn the coarse adjustment while looking through the eyepiece until the slide is in focus.

5. Move the slide up/down and left/right on the stage to change what you see in the eyepiece.

6. When you have found what you are looking for, click in the low power (larger lens should have a 10 on it).
7. Turn the fine adjustment no more than 2 full turns in either direction to get your object in focus.

8. Click in the high power (even larger lens should have a 40 on it).

9. Turn the fine adjustment no more than 1 full turn in either direction to get your object in focus.

10. If at any time, you cannot get the object in focus, try going to a smaller lens (from high power to low power and from low power to scanning) and then getting the object in focus.

11. Clean up the microscope by, clicking in the scanning lens. Remove the slide. Unplug the microscope. Carry (by the arm and the base!) the microscope back to its proper place.
