Optical CVD Diamond Specification

Next-Gen Photonic Material for Extreme Environments
Dominating optical performance with the industry’s widest transmission band (225 nm - 25 μm, skip 1.8-2.5 μm), CVD single-crystal diamond adds microwave transparency to its unique portfolio. Unmatched radiation resistance, Vickers hardness >100 GPa, 2,200 W/mK thermal conductivity, chemical stability, and ultra-low expansion establish it as the benchmark IR window material.
