MVN Series Precision Vertical Travel Stages provide precise manual height control with micron-scale sensitivity. Their high load capacity makes them especially suited to vertical positioning of heavy payloads.
The stage utilizes an inclined plane design consisting of two precision-machined, opposing wedge blocks. Horizontal translation of the lower wedge is transformed into vertical motion of the upper wedge by means of inclined ball races. For linear, backlash-free travel, ball races are fabricated from precision-ground tool steel and are pre-loaded by a spring. A rotation of one division on the micrometer scale corresponds to a vertical displacement of 5 µm. Actual manual positioning sensitivity is about 1 µm using a standard micrometer.
These stages have large mounting platforms that incorporate an array of tapped English or metric mounting holes for the convenient attachment of components.
