Application context
Correct pointing drift and low-frequency jitter before it reaches the sample or detector.
Steer a beam across a field or modulate its position faster than any stage can move the sample.
Hold a transmitted beam on a distant aperture as the mount and building move.

Technical FAQ
Travel range(closed-loop): 12 um, 1 mrad, 1 mrad · Resolution(open-loop): 0.2 nm, 0.05 urad, 0.05 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.
Resolution(closed-loop): 0.4 nm, 0.1 urad, 0.1 urad · Controller: MC-Archimedes.N 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.
Resonant Frequency(no load): 5.5 kHz. 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
These use SGS sensors rather than capacitive, trading ultimate linearity for the millisecond response beam stabilisation needs. Closed-loop range is ±1.5 mrad on the 0303 and ±5 mrad on the 1010, with 0.1 to 0.5 µrad closed-loop resolution.
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.
