Q

How do you use a light microscope?

A
  • plug in the microscope and turn on the light
  • turn the rotating nose piece so that the lowest power lens is in place
  • prepare the sample on the slide and place it on the stage
  • using the coarse focus knob raise the stage til it is at the highest point
  • while looking through the eyepiece move the coarse focus knoband bring the slide into focus
  • use the fine focus knob til the cells are focused.draw what you see
  • next, view the specimens under medium and high power
