The 800 precision lift provides precise control of vertical motion throughout approximately ½" (13mm) range.  It is generally used for fine vertical positioning after the instrument height has been roughly established with a stand column.  A large diameter, fine-motion screw allows minute height adjustments of previously leveled instruments fast and easy, while minimizing the need to re-level the instrument.  Internal guideways also minimize any azimuth (rotational) shifting.  The 800's 2.825 x 20 external thread fits into many of the intermediate tubes on our stands.  On top, a recessed dovetail receptacle provides the interface for our lateral slides and other products.  You can orient these products in any azimuth direction desired once inserted in the dovetail socket.  Socket head set screws then tighten on the inserted dovetail and hold it firmly in place.
