PIglide RLA Rotation Stage with Air Bearings, Large Aperture Friction-free, Motorized A-68x  365 mm diameter motion platform, 260 mm diameter aperture  Low profile  Eccentricity and flatness < 300 nm Product overview The directly driven flat rotation stages of the PIglide RLA series are designed for the highest precision. They have a low profile and a large clear aperture. The RLA stages offer a superior travel accuracy, flatness, and wobble performance.  Brushless  Low cogging torque Absolute encoder (optional) Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation. Incremental or absolute encoder PIglide filter and air preparation kit Single or multi-axis motion controllers and servo drives Multi-axis/customized setups Base plates made of granite and systems for reducing vibration Application fields Tomography, beamline systems, wafer metrology, wafer inspection, measuring technology, inspection systems, calibration, scanning. Thanks to the friction-free motion, no particles are formed, which makes PIglide stages ideal for cleanroom applicat
