Omniax Translator



General Handbook

Replacing Lead Screw


The Omniax is a highly versatile translator designed for excellent stability without compromise. The large variation of modules available for the Omniax means that suitable configurations can be matched to the most extreme applications. Long travels, multiple rotations, specimen rigidity, its capacity for feedthroughs and sheer versatility mean that the Omniax has been used as the basis for the Cryoax and Helistat cryostats and CTPO 6 axis goniometer for many years. The Omniax continues to offer excellent value at an unrivalled level of quality that makes this impressive translator the best selling double bellows translator on the market.

Features
  • The Omniax is a fully UHV compatible double bellows translator with large probe capacity.
  • The Omniax uses the unique VG Scienta hinged flange and guided support tube to eliminate deflection due to vacuum loading and for extreme stability.
  • The standard Omniax support tube is typically 5 times more rigid than that of the Transax or 25 times that of a conventional support tube.
  • The Omniax has large load carrying capacity and can accept probes up to 50mm diameter even with ±25mm XY travel.
  • The construction is thermally matched to eliminate bi-metal deformation even after repeated bakeouts to 230°C
  • All axes can be manually or stepper motor operated to high resolution and repeatability levels. The actuator position can be moved to opposite sides for convenience. The motors are exceptionally easy to remove for bakeout.
  • The interchangeable modules allow for most configurations to be updated later.
  • The Omniax conforms to EU Safety Directives.

Construction
The stability and versatility of the Omniax is possible due to the double bellows construction. No compromises are made in order to achieve the best stability possible for long travel manipulation: thermally matched components, spring mounted linear bearings, anti-backlash drives, the hinged knee, cross roller slide-ways, recirculating ball linear guide bushes, and very robust construction are some of the reasons for the claim that the Omniax cannot be beaten if the positional stability of your sample is important.
