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 42 millimeters of travel in only three revolutions. The fine adjustment is controlled by a large 1.5- inch diameter knob that is attached to a 100TPI adjustment screw which moves the stage across 3 millimeters of travel. This large knob improves leverage and control of any fine adjustments so that movement ap­proaching submicron accuracies can be achieved.
