Detailed explanation-1: -Coarse and fine adjustment The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.
Detailed explanation-2: -The coarse adjustment knob is used to focus the object. This knob is used with the low power objective lens as well as the scanning objective lens.
Detailed explanation-3: -The coarse adjustment knob should only be used in the scanning objective lens because it moves the stage up and down in bigger increments and brings it closer to the lens faster, bringing it into focus.
Detailed explanation-4: -Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above). Microscopes with in-stage condenser lenses render a sharper image than those with no lens (at 400x).
