Modular Fast Travel Stages

   The DT-130 series of dovetail stages integrates a coarse fast travel stage and a fine adjustable stage in one simple device.  The coarse fast action is controlled by a 0.74-inch diameter knob that is attached to a multi-lead adjustment screw that drives the stage across 38 millimeters of travel in only three revolutions.  The fine adjustment is controlled by a large 1.51-inch diameter knob that is attached to a 100TPI adjustment screw which moves the stage across 3.5 millimeters of travel.  This large knob improves leverage and control of any fine adjustments so that submicron accuracies can be achieved.
   Three models of the DT-130 series are available:  single-axis DT-130-X, two-axis DT-130-XY and three-axis DT-130-XYZ. The XY and XYZ versions employ a unique sliding clamp that attaches to the V-groove on the top or bottom of the stage.  This simple clamp allows the user to select the location of the orthogonal stage anywhere along the 3.0 inch length of the stage.  This clamp is also available as a two-piece angle bracket for creating customized subassemblies.
