While this microscope has a coarse adjustment by rack and pinion, it lacks a formal fine adjustment. To make up for the lack of a fine adjustment, a long brass rod is attached to the pinion of the main focusing adjustment thus, effectively, increasing the radius of the pinion allowing  it to turn more slowly than it would if the knobs were used.
