Toepassingen
Werken met meerdere monsters
Wissel tussen meerdere monsters op één houder zonder het systeem te openen en op te warmen.
Overzicht en daarna inzoomen
Doorkruis het volledige monsteroppervlak om een interessegebied te vinden en geef het door aan een fijnscanner.
In en uit het bundelpad
Breng een monster, filter of referentie tijdens een meting in en uit het optische pad.
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.
