Application context
Why this design is used
Optical scanning and dithering
Steer a beam across a field or modulate its position faster than any stage can move the sample.
Free-space link alignment
Hold a transmitted beam on a distant aperture as the mount and building move.
System integration
Integration and compatibility
Use these checks to connect Mirrors.Z12 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(open-loop): 15 μm · Travel range(closed-loop): 12 μm
- 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
- Resolution(closed-loop): 0.2 nm · 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): 4 kHz · Max. Payload (horizontal mounting): 200 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 Mirrors.Z12
What travel and resolution does the Mirrors.Z12 provide?
Travel range(open-loop): 15 μm · Travel range(closed-loop): 12 μm. 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.

Matching connectors do not guarantee electrical compatibility.
What load can the Mirrors.Z12 carry, and how does it mount?
Resonant Frequency(no load): 4 kHz · Max. Payload (horizontal mounting): 200 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
Strain gauges, because bandwidth beats linearity here
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.
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.
