Thorlabs' XR50 Series Translation Stages provide 50 mm of linear translation with less than 150 µrad of deviation per axis in pitch and yaw over the full range of the stages. These stages use crossed-roller bearings to support precision motion and high load capacities.

Thorlabs offers four rail carriers that are directly compatible with our XR25 and XR50 series stages, providing coarse translation in addition to the fine translation supplied by the stage's micrometer, as well as expanding the stages' threading options for optomechanical assemblies.
