Diamond Crystals

Due to its unique combination of extraordinary physical properties, single crystalline diamond (SCD) 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.
