Closed-loop raster scanning
Capacitive feedback linearises the scan, removing the hysteresis that distorts open-loop images.

Application context
Why this design is used
Scanning probe microscopy
Provide the fine XY or XYZ scan under an AFM, STM or near-field head.
Confocal and Raman mapping
Step a sample through a focus in reproducible increments so map pixels correspond to real coordinates.
System integration
Integration and compatibility
Use these checks to connect SD15/30.X.C 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(closed-loop): 30 μm · Resolution(closed-loop): 0.2 nm
- 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-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.
- Load and mounting
- Resonant Frequency(no load): 2.2 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.
Technical FAQ
Integration questions for SD15/30.X.C
What travel and resolution does the SD15/30.X.C provide?
Travel range(closed-loop): 30 μm · Resolution(closed-loop): 0.2 nm. 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 SD15/30.X.C require?
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.
What load can the SD15/30.X.C carry, and how does it mount?
Resonant Frequency(no load): 2.2 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
What this model has to survive, and what it needs around it
Closed-loop travel is shorter than open-loop travel
The loop reserves headroom to correct within, so the usable range drops when the sensor is engaged: an S100.XY.C covers 120 × 120 µm open-loop against 100 × 100 µm closed-loop, and an S200 covers 240 × 240 against 200 × 200. Specify against the closed-loop number.
Flexure guiding, capacitive sensing
A piezo stack acting through flexure hinges with a capacitive sensor reading directly against the moving surface — no sliding contact, no backlash, and millisecond-class response.
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.
