PI USA offers the UPR-120 AIR ultra-precision rotation stage by PI miCos. This high-end rotary positioner excels with dynamic positioning capabilities and very high accuracy. The custom air-bearing design achieves flatness and eccentricity of 0.1μm with wobble of 1.25 μrad. A direct measuring optical encoder provides repeatability to 0.00005 degrees and a double read-head option is available when the highest accuracy and repeatability are required.
High dynamics are guaranteed by means of a direct-drive torque motor. The UPR-120 is a member of a large family of precision rotation stages with air bearings and mechanical bearings for ambient and vacuum environments.
In addition to the air bearing stages, stages with traditional high precision bearings are also available. They come with worm gear drives and are offered with stepper motors and servo motors with rotary encoders. A miniature stage series for small loads is also offered as well as a stage for polarization rotation.
