Fast Z-sectioning
Move the objective instead of the sample, so optical sections can be stepped without disturbing live specimens.

Application context
Why this design is used
Autofocus and focus tracking
Hold focus against thermal drift over acquisitions lasting minutes to hours.
Light-sheet and multiphoton stacks
Acquire Z-stacks at a rate set by the scanner rather than by the microscope frame.
System integration
Integration and compatibility
Use these checks to connect Carrier.OB400.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: 400 μm · Resolution(open loop): 0.8 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
- Resolution(closed-loop): 5 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): 380 Hz
- 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
Driving the objective rather than the sample
Moves the lens along the optical axis for focus stacks and z-series, leaving a liquid sample or mounted cell undisturbed. Travel options run 100, 200 and 400 µm; settling time rather than range is usually the limiting specification.
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.
