RS-40 V7 Compact Rotation Stage Suitable for Vacuum
Precision Positioning
- Vacuum compatible 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 spindle a material with particularly low outgassing is used. This allows a bakeout temperature of up to 80° C.
Higher quality for applications in high vacuum
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 and the spindles and guides are made of stainless steel. With this, the PI V7 vacuum class is reached, which means up to 10-7 hPa.
Drive
Stepper motor with gearhead.
Application fields
Vacuum chambers. Research. Beamline instrumentation. Microscopy. Electronics assembly and inspection.
