Construction

 

   The central axle is a semi-rolling cylindrical axle system, with high precision and automatic centering. The graduated circle and vernier are mounted on the axle and rotate with it together (may also be coupled with the object stage). The telescope is coupled with the vernier and rotate with it together. Both the graduated circle and vernier are equipped with fine adjusting screws and locking device so as to achieve fine adjustment.

    The optical system is composed of Abbe type autocollimating telescope, variable slit collimator and graduated circle and vernier with illuminating telescope is normal to a reflecting mirror, the green cross will be oriented at a given distance from the central cross wire. Move the eyepiece to and fro so as to put the graticule in focus.
