Compact Rotation Stage Suitable for Vacuum Precision Positioning  Suitable for vacuum up to 10-7 hPa  Unlimited travel range  Repeatability to 87 µrad  20 mm Ø aperture  Reference switch Standard-class rotation stage Worm drive. Aperture with 20 mm Ø. Reference switch. Reduced outgassing especially for use in vacuum environments Most notably, for the lubrication of the guides and the drive screw a material with particularly low outgassing is used. Therefore, a bakeout temperature of up to 80 °C can be reached. Higher quality for high vacuum applications In this case, special components suitable for high vacuum are used, such as motor, measuring system, and limit switches. In addition, the surface is made of uncoated aluminum, the drive screw and guides are made of stainless steel. With this, the PI -7 V7 vacuum class is reached, which means up to 10 hPa. Stepper motor with gearhead. Application fields Vacuum chambers. Research. Beamline instrumentation. Microscopy. Electronics assembly and inspection.
