About UHV Slits

Our classical IB-C30-UHV slit has been on the market for more than 10 years and performs successfully at numerous facilities around the world. Following the increasing demand, other even more advanced, UHV-slit designs have followed.

At JJ X-Ray, we have extensive knowledge of and experience with UHV mechanics that makes it possible to customize solutions to meet the specific requirements of our customers.

Common features:

  • Assembled in a fully equipped ISO 5 cleanroom.
  • Customization according to customer requests (blades, flanges,
    motors, encoders, connectors, fiducial plates, etc.).
  • Helium leak detection and residual gas analysis (RGA) as an integrated part of the Factory Acceptance Test.
  • Options for fiducialisation, laser interferometry and vibration measurement.
