Wobble Sticks

The UHV Design wobble stick is a slimline modular concept benefiting from UHV Design’s high power magnetic coupling technology.

The coupling eliminates the need for long edge-welded bellows stacks, typically employed with conventional wobble stick designs

This reduces the risk of leaks, particularly for deposition applications such as MBE where particulates or deposition between bellows

convolutions can reduce lifetimes or cause rapid and catastrophic failure. Also, unlike a bellows-sealed device, the wobble stick is not

subject to the thrust due to vacuum, resulting in smooth, free-moving operation.

The WS40 wobble stick series provides linear, rotary and tilt manipulation. The WSG40 series comprises an additional hand-operated

trigger mechanism to activate the end gripper. In-line and right-angle versions are available which can are supplied as standard without an

end-effector. If preferred the WS40 and WSG40 can be supplied with a choice of standard end-effector options for flag, puck and ESCA

stub sample holders.

The WS40 series provides linear motion and rotation of the vacuum shaft with +/-22° tilt allowing precise manipulation of a range of

sample holders.

Magnetic coupling technology eliminates the need for edge-welded bellows. This reduces the risk of leaks and in doing so,

improves the reliability of the system for sensitive applications.

Unlike conventional bellows-sealed wobble sticks there is no resistance to linear motion due to vacuum thrust.

RotarySource Shutters

Magnetically-coupled wobble stick with a choice of 100mm to 350mm linear stroke, rotation and +/-22° tilt. Smooth, free-running operation with no thrust due to vacuum.

Available with a choice of end effector options for flag, puck and ESCA sample holders.

WSL KEY ADVANTAGES

» Rotation with +/- 22° tilt

» 100mm to 350mm linear stroke

» In-line and right angle versions

» No thrust due to vacuum, smooth reliable operation

» Bakeable to 250°C without removing any components
