Our optical grade CVD (Chemical Vapor Deposition) diamond plates are engineered for the most demanding high-power laser, thermal management, and optical window applications. Thanks to their exceptional spectral transmittance (from ultraviolet to far-infrared) and ultra-high thermal conductivity, these plates are widely utilized as protective windows for high-power CO2 lasers, spectral output windows for infrared spectroscopy, semiconductors, and advanced optical components. At INFI ADVANCED MATERIALS CO.,LTD, we have been growing alongside China's advanced materials industry since 1993, providing dependable diamond solutions to famous research laboratories, universities, and leading optical manufacturers globally.
Quality control is at the core of our manufacturing process. INFI ADVANCED MATERIALS CO.,LTD is proud to host the only designated testing center of Jilin University in Hunan Province. Our state-of-the-art facility is fully equipped with highly precise analytical instruments, including infrared spectrometers to verify spectral absorption, 200-1000x electron microscopes for surface analysis, magnetic susceptibility analyzers, and particle size analyzers. Operating dedicated CVD growth chambers alongside advanced laser cutting, grinding, and polishing systems running day and night, we ensure that every optical plate meets strict standards for minimal nitrogen impurities, excellent flatness, and outstanding transmission rates.
We provide complete, end-to-end CVD diamond synthesis, laser cutting, polishing, and grinding services tailored to your exact specifications. Whether you require specific rectangular geometries, circular windows, or precise thicknesses, our technical team can customize the dimensions and finish. Our standard options include double-sided polished plates with optical-grade surface roughness (Ra<5 nmRa<5 nm or customized target specifications) to minimize scattering losses in laser systems.
INFI ADVANCED MATERIALS CO.,LTD handles international shipments smoothly under flexible Incoterms including FOB, CFR, CIF, and EXW, dispatching from major international shipping hubs like Changsha, Guangzhou, Shanghai, and Shenzhen. For standard in-stock CVD substrates, we dispatch within 5 working days. For custom-fabricated optical CVD plates, our average lead time is within 15 working days regardless of peak or off-peak seasons. We accept secure payment methods including T/T, PayPal, Western Union, Small-amount payment, and Money Gram to facilitate safe global transactions.
