Z Wedge Stages

Z Wedge Stages

Nanomotion Z-wedge stage utilizes crossed roller bearings on an incline to drive a center wedge through a top and bottom plate that are coupled together. This horizontal motion results in pure vertical translation of the top surface of the stage. Using a Z-wedge configuration facilitates easy access over the entire surface and from all sides. Linear position encoding is done directly on the vertical translation eliminating any errors from the angle of the wedge.
