Newport MVN50 Vertical Translation Stage / Lab Jack with Micrometer

Description

Newport model MVN50 high precision vertical translation stage in excellent mechanical and cosmetic condition. 8mm vertical travel range, 5 um per division resolution with included Newport BM11.16 micrometer.
The MVN50 Precision Ball Bearing Vertical Linear Stage provides precise 0.31 inch manual height control with micron-scale sensitivity. Its high load capacity makes it 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 half the linear displacement distance, thereby doubling the sensitivity. Manual positioning sensitivity can be approximately 50 nm using the DM series of differential micrometers. This stage has a large mounting platform that incorporates an array of tapped English mounting holes for the convenient attachment of components.
