  1. What is the compound light microscope used for?
    to magnify small thin, transparent objects using transmitted light
  2. What is the dissecting microscope used for?

    • -oil immersion lens (100x or 1000)
  6. What does the iris diaghragm do?
    regulates the amount of light permitted to pass through the condensor and reach the stage
  7. What is Parafocal?
    when material is in good focus at low power, it still will have good focus in another
  8. Working distance is what?
