CVD Diamond Crystal Material General Description
Chemical Vapor Deposition (CVD) Diamond Crystal is an advanced material with exceptional physical, thermal, and optical properties. Produced under controlled conditions, CVD Diamond Crystal leverages sp² and sp³ hybridized bonds, resulting in unmatched mechanical strength and chemical stability. CVD diamonds can be synthesized as single crystals or polycrystalline layers, enabling diverse applications in optics, electronics, and laser systems.
Optical-grade polycrystalline CVD diamonds have low absorption rates in UV, visible, and IR wavelengths, making them excellent candidates for high-power laser optics. The material demonstrates superior thermal conductivity and hardness, extending its usability to extreme temperature ranges above 2000°C. POC offers high-quality single and polycrystalline diamonds tailored to meet specific optical and mechanical needs.
