Focusing the Mlerescope 1. Turn the nosepiece until the lowest power obiective lens (4x - shortest objective) is in straight alignment over the stage. Turn until you feel or hear a click. 2. Always begin focusing with the lowest power obiective lens-4X (scanning power). 3. Place a slide with the word "ro" on the stage, clin in place Center the word "roo" in the middle of the stage over the light source aperture. 4. With the course adjustment knob, raise the stage until it stops 5. While viewing through the eyepieces slowly turn the course adjustment knob (lower the stage) until the printed "roe" comes into rough focus. 6. Use the fine focus adjustment knob to sharpen the focus. 7. Adjust the light diaphragm lever until the word "oe" is in good contrast. Note: You can adjust the occular lens few pieces) to compensate for differences in your eyes. Close one eye and focus the slide with the stage focus knobs. Now close this eye and open your other eye and turn the ocular lens for this eye until the slide comes into focus. // yow wear prescription glasses you might find it easier to remove them when you use the microscope. Yow can also adjust the ocular lens to match the distance between your pupils. You can push or pull the ocular lens together or apart to match your pupil distance. Do this if you see two circular fields of view Inversion of Image 1. In the space provided, draw the word "oe" as it appears on the stage (look directly at the slide, not through the eyepiece) 2. Now look through the eyepieces and diagram the word "roe" as it now appears. Image without microscope Image with microscope 3. Describe the difference in how the word "roe" appears through the microscope. 4. Move the slide to the right while viewing through the eyepiece. Which direction does the word "roe" appear to move? 5. Move the slide towards you. Which direction does the word "roe" appear to move?

Answer 1

1) Image without microscope Image with microscope Roe Əoy 2) Under the microscope, the image is magnified but it is also inverted. This is because the lenses in the microscope act as mirrors, magnifying the image but showing the image upside down. 3 and 4) Since you are observing the upside down image, every action that you make will be the opposite under the microscope. So if you move to the right, the image will move to the left. If you move the slide toward you, it will actually move to the opposite direction under the microscope.
