Diamond Crystals

Due to its unique combination of extraordinary physical properties single crystalline diamond is of great interest for advanced optical and electronic applications. Examples include optical spectrometer windows, high power density X-ray monochromators, intracavity heat spreaders for solid-state lasers and electronic applications requiring n- or p-type doped crystals. Over the past decade synthesis technology for making single crystal diamonds has significantly improved with the goal to produce the material in larger quantities, larger areas and more cost effectively. We offer the fabrication of crystals tailored to our customers specifications.

Specifications

  • Single crystalline diamond
  • Thickness of up to severeal millimeters
  • Lateral dimensions per seed of up to 7 x 7mm2
  • Simultaneous deposition on up to 88 crystals
  • Boron doping (p-type) for conductive and blue diamond
