Focus mount Knob: Stereo microscopes usually have one focus knob. Helps move the head of the microscope up and down to bring a sharp image of the object. Most dissecting microscopes have standard “rack and pinion” focusing. Rack is the track with teeth and pinion is the gear that rides on the teeth. The knob helps the pinion move along the rack.
