Technical FAQ
Travel range: ±8 ° · Unidirection Repeatability: ±10 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.
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.
Max. Payload (horizontal mounting): 1 kg. 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
Each goniometer tilts about a centre a fixed height above its own mounting surface, so a theta and phi pair share one virtual pivot. Get that height right against your sample plane or the beam walks as you tilt.
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.
