The main focus utilized with this microscope operates on the stage by rack and pinion. The tube remains stationary and has a fine adjustment operated by the milled knob attached to the tube which moves the nosepiece. The microscope is designed to pivot upon its pillar. Another microscope by the same makers with a similar focusing arrangement can be found elsewhere on this website.
