Custom Diamond Assemblies

Applied Diamond offers diamond parts brazed to a variety of materials, including stainless steel, Inconel, Kovar and Cooper Nickel/Moly.

Examples of our work include:

  • Thin SC diamond  windows is for a vacuum-based power amplifier operating in the sub-mm regime, hermetic and bakeable to 200-300degC as an assembly.  Brazed to a moly, cooper nickel holder
  • Polycrystalline diamond thickness of 10 um and an open aperture of 3 – 5 mm diameter brazed to Kovar holders for an x-ray application.  The joint between the two will be vacuum-tight, vacuum-compatible, thermally conductive and suitable for high temperature use (>700C).
  • SC diamond brazed to a copper ring and Inconel holder, then laser welded into an Inconel plate, electroplated with 12 um of nickel and  2 um of gold.   The application is for a Synchrotron Light Source.
  • A 30 mm polycrystalline diamond brazed to a copper ring and stainless steel UHV flange. Completed parts will be certified to a leak rate of less than 1×10-9cc/second under a partial pressure of helium for 1 minute.
