Parts of a Microscope

Care and Handling of a Microscope

Transporting a Microscope When you pick up a microscope and walk with it, grab the arm with one hand and place your other hand on the bottom of the base.

Handling and Cleaning Never touch the lenses with your fingers. Your body produces an oil that smudges the glass. This oil can even etch the glass if left on too long. Use only LENS PAPER to clean the glass. TOILET PAPER, KLEENEX, AND PAPER TOWELS HAVE FIBERS THAT CAN SCRATCH THE LENSES.

Storage When you are finished with your "scope" assignment, rotate the nosepiece so that it's on the low power objective, roll the nosepiece so that it's all the way down to the stage, then replace the dust cover.

Clean up Clean all slides, materials, and work area when you're done. Please, be careful with the slides and cover slips. They are made of glass and if broken, you will get cut and you will bleed. DON'T CUT YOURSELF.

Follow these directions when using the microscope!

1. To carry the microscope grasp the microscopes arm with one hand. Place your other hand under the base. 2. Place the microscope on a table with the arm toward you. 3. Turn the coarse adjustment knob to raise the body tube. 4. Revolve the nosepiece until the low -power objective lens clicks into place. 5. Adjust the diaphragm. While looking through the eyepiece, until you see a bright white circle of light. 6. Place a slide on the stage. Center the specimen over the opening on the stage. Use the stage clips to hold the slide in place.

7. Look at the stage from the side. Carefully turn the coarse adjustment knob to lower the body tube until the low power objective almost touches the slide. 8. Looking through the eyepiece, VERY SLOWLY turn the coarse adjustment knob until the specimen comes into focus. 9. To switch to the high power objective lens, look at the microscope from the side. CAREFULLY revolve the nosepiece until the high-power objective lens clicks into place. Make sure the lens does not hit the slide. 10. Looking through the eyepiece, turn the fine adjustment knob until the specimen comes into focus.
