The Fine Adjustment
All magnification
The fine adjustment, the two little knobs on both sides of a compound microscope, is rotated to move the body tube down or the stage up in tiny distances to help you focus in HIGH power.The fine focus knob is geared with a different ratio than the coarse knob to "fine tune" your focus. It allows for tiny adjustments to the focus setting, rather than larger ones.
