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 egde-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 immediate failure.


Key Features

  • In-line and right-angled version with +/-22o tilt
  • 100-350mm stroke range (50mm increments) 
  • Note: longer strokes are available upon request. Contact us for details.
  • Bakeout to 250oC without the need to remove the outer magnet assembly
  • WSG40 includes trigger grip
  • Choice of end effectors for flag, puck and esca stub (see below)
  • No thrust due to vacuum
