Optical-Grade Single Crystal CVD Diamond: Superior Light Transmission
CVD-grown diamond achieves unmatched optical performance with the broadest transmission spectrum among solids – spanning 225 nm (UV) to 25 μm (IR) excluding 1.8-2.5 μm – plus exceptional microwave transparency. Its unique fusion of radiation resistance, extreme hardness, thermal conductivity, chemical inertness, and ultra-low expansion establishes it as the premier infrared optical window solution.
