Application context
Why this design is used
Sample orientation
Bring a facet, crystal axis or device feature to the measurement angle and hold it there.
Angle-resolved scattering
Drive azimuthal sweeps where angular repeatability sets the quality of the dataset.
System integration
Integration and compatibility
Use these checks to connect RS35.Lab to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Travel and resolution
- Travel range: 360 ° · Unidirection Repeatability: ±7.5 urad
- Separate travel from resolution and both from repeatability. Repeatability is what an automated sequence actually depends on, and it is the figure most often absent from a headline specification.
- Drive and feedback
- Controller: MC-Newton.S series
- Pair open-loop mechanics with the specified high-voltage or inertial driver, and closed-loop variants with the controller their capacitive, strain-gauge or encoder feedback requires. Matching connectors do not guarantee electrical compatibility.
- Load and mounting
- Max. Payload (horizontal mounting): 500 g
- Check the load rating in the orientation you will use it — a vertical or cantilevered load is a moment, not a mass — and match the base to an M6 pattern on a 25 mm grid or a 1/4"-20 pattern on a 1 inch grid.

Integration questions for RS35.Lab
What travel and resolution does the RS35.Lab provide?
Travel range: 360 ° · Unidirection Repeatability: ±7.5 urad. Separate travel from resolution and both from repeatability. Repeatability is what an automated sequence actually depends on, and it is the figure most often absent from a headline specification.
Which controller does the RS35.Lab require?
Controller: MC-Newton.S series. Pair open-loop mechanics with the specified high-voltage or inertial driver, and closed-loop variants with the controller their capacitive, strain-gauge or encoder feedback requires. Matching connectors do not guarantee electrical compatibility.
What load can the RS35.Lab carry, and how does it mount?
Max. Payload (horizontal mounting): 500 g. Check the load rating in the orientation you will use it — a vertical or cantilevered load is a moment, not a mass — and match the base to an M6 pattern on a 25 mm grid or a 1/4"-20 pattern on a 1 inch grid.
Specifying this part
What this model has to survive, and what it needs around it
Rotary resolution sits well above the linear axes
Rotary encoders read to around 50 nm equivalent rather than the 2 nm of the linear stages. If angular repeatability drives the measurement, check it against the encoder figure rather than assuming the linear specification carries across.
Vacuum and non-magnetic versions
Most of the range is orderable as .HV (high vacuum), .UHV (ultra-high vacuum) or .NM (non-magnetic). The suffix changes materials, cabling and bake compatibility rather than the mechanics, so specify it against the chamber the stage will live in.
