Foil Collimators

Building on thorough experience, JJ X-Ray has over the years provided numerous of collimators to both neutron and x-ray communities all over the world.

The collimating foils are typically made of a thin PETP or Kapton sheets with a coating of Gadolinium Oxide (Gd2O3) or enriched Boron-10 Carbide (10B4C). The individual foils are supported using a stretch-foil technique where they are positioned and slightly stretched between accurately machined spacers. The result is a robust and cost efficient solution.

Some designs will, however, require additional solutions, such as individual tensioning of the foils and unique tools for generating some of the more complex geometries. Non-magnetic materials and vacuum compatibility are also common features.

Our collimators are designed to meet each customers specific needs. The profound knowhow that we have gained, under such customized conditions, is an invaluable part of what JJ X-Ray applies to each and every one of our collimators.

In our collimator catalogue, you will find a small extract of our portfolio. The examples illustrate the variety of designs and geometries.
