CRYO TIP / TILT / PISTON STAGE (CTTPS)

Cryogenic tip tilt stage (+ piston motion) with nanometer accuracy

CONFIGURATION

FEATURES

 Driven by Cryo Linear Actuators
Preloaded to ensure play free actuation
Membrane eliminates erratic lateral motion
Materials: stainless steel, titanium
20 mK to 375 K, vacuum compatible
Sub-nanometer stability
1/2″ or 1″ version standard
Optics side-clamped with a spring loaded screw
Self locking; no power dissipation when “off”

DESCRIPTION

The Cryo Tip / Tilt / Piston Stage (CTTPS) accepts 1/2″ or 1” optical elements and can be operated in a cryo-vacuum environment. It is actuated with JPE’s Cryo Linear Actuators (CLA). Play of the tip / tilt / piston functionality is eliminated by built-in preload springs. Lateral position is not achieved via traditional v-groove constructions, but by using a deformable metal membrane. This feature not only eliminates play but also the erratic motion seen in the traditional designed tip tilt piston stages. The optics are clamped from the side with a single spring loaded screw.
