8mm Dia., 0.5mm Thick, Coherent Uncoated Polycrystalline CVD Diamond Window

Product Details High Transmission Across UV, FIR, and Microwave Spectra High Thermal Conductivity for Use with High Power Lasers Exceptional Hardness for Ultimate Scratch Resistance Coherent Manufactured Coherent Optical Grade Polycrystalline CVD Diamond Windows feature high transmission across the ultraviolet (UV), far infrared (FIR), and microwave wavelength spectra. Manufactured from plasma chemical vapor deposited diamond by Coherent, these windows offer high-purity, uniformity, and ultimate scratch resistance. These windows also have exceptional chemical resistance and biocompatibility, enabling their use in harsh environments as well as in medical applications. Coherent Optical Grade Polycrystalline CVD Diamond Windows are used as exit windows of high-power CO 2 lasers, offering higher thermal conductivity and lower absorption than other infrared materials to minimize effects on beam quality. Other common applications include their use as microwave windows in diamond-based nuclear detectors, general microwave engineering, and multi-spectral optic systems. Custom coating opportunities, including anti-reflection and high-reflectivity coatings, are available. Please contact us for more information. Note: II-VI Incorporated is now Coherent Corp.
