CVD Lab Grown Diamonds | Hard Chemically Stable and Low Coefficient of Expansion

Optical-Grade CVD Single Crystal Diamond: Unmatched Spectral Performance
CVD-grown single crystal diamond delivers the broadest light transmission range among solid materials, spanning 225 nm (UV) to 25 μm (IR) – excluding the 1.8–2.5 μm band – with exceptional microwave transparency. Its unique combination of radiation resistance, extreme hardness, thermal conductivity, chemical inertness, and minimal thermal expansion makes it the premier choice for advanced infrared optical systems.
