The coarse adjustment knob should never be used when viewing slides under high power magnification or with oil immersion lenses. Using it in these instances can lead to damaged slides or lenses due to the increased risk of the objective lens coming into contact with the slide.

FAQs & Answers

  1. Why should the coarse adjustment knob not be used with high power lenses? Using the coarse adjustment knob with high power lenses can cause the objective lens to hit the slide, potentially damaging both the lens and the slide.
  2. What is the risk of using the coarse adjustment knob with oil immersion lenses? The coarse adjustment knob can cause the oil immersion lens to make contact with the slide, risking damage to the lens and compromising image quality.
  3. How should one focus under high power magnification if not using the coarse adjustment knob? Focus should be done using the fine adjustment knob under high power magnification to make precise and safe focal adjustments.
