Applications
Multi-sample handling
Move between several samples on one holder without opening and rewarming the system.
Wide-field survey then zoom
Traverse the full sample area to find a region of interest, then hand over to a fine scanner.
In/out of beam path
Insert and retract a sample, filter or reference from the optical path during a run.
Specifying this part
What this model has to survive, and what it needs around it
Displacement, not resolution
The LS series covers 30 to 200 mm of closed-loop travel with roughly 150 nm sensor resolution and 1–2 µm repeatability. It is the right choice for sample load-locks, filter exchangers and long-stroke scanner positioning, not for fine tracking.
Heat load at the cold plate
Stick-slip inertial drives dissipate energy per step and draw no holding current once stopped, so the steady-state load on the mixing chamber is the wiring loom rather than the motor. Anchor the loom at each temperature stage and thermalise the moving body with an FTC copper braid.
Non-magnetic construction
Titanium bodies and BeCu fasteners throughout, rated for operation to 35 T and down to 30 mK with the .ULT option, at 2 × 10⁻¹¹ mbar with .UHV. A single steel screw substituted at installation is enough to compromise a high-field assembly.
