Linear Shifts

UHV transfer mechanism fabricated from a pair of flanges, connected by an edge welded bellows.

Manufacturer

Prevac

Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.

Description

The free flange moves towards the fixed flange in a controlled, precise motion whilst maintaining parallelism. Its action are similar to the Z slide manipulator, but with slightly reduced travel length and overall positioning resolution. The standard mounting flange is DN 40CF or DN 63CF. The shift is actuated by a handwheel and can work in any orientation.

The linear shifts are designed for the linear movement of instruments with minimum tilt or wobble in the movement, maintaining precision alignment before and after the pump-down.

Applications

The linear shifts are used in applications that don’t require the higher precision and graduated movement of other linear motion devices. They are usually used for:

  • manipulation of surface science tools with respect to the sample position,
  • manipulation of evaporation and sputter sources,
  • manipulation of electron and x-ray sources,
  • manipulation of quartz oscillators,
  • sample transfer applications.
