Single Crystal CVD Optical Diamonds | Round Optical Window Premium Choice
Round Optical Single Crystal CVD Diamonds
Featuring exceptional optical and physical properties, optical-grade CVD single crystals provide excellent transmission, high-quality crystal structure, dimensional stability, wear resistance, and thermal stability. They satisfy rigorous requirements for optical equipment, improving reliability and performance in diverse optical fields.
Key Properties
With broad wavelength transmission and low IR scatter, CVD diamond is chemically inert and extremely hard. This makes it optimal for high-power, large-area applications needing strength and hazardous material resistance. Such capabilities permit compact material geometries for lightweight solutions, while diamond processing innovations address new optical problems.
