| titleOfInvention | Thick optical quality synthetic polycrystalline diamond material with low bulk absorption and low microfeature density |
| abstract | A polycrystalline chemical vapour deposited (CVD) diamond wafer comprises: a diameter ≥ 40 mm; a thickness ≥ 1.0 mm; an absorption coefficient ≤ 0.1 cm-1 at 10.6 μm; and a microfeature density meeting the following specification: in a central area of the polycrystalline CVD diamond wafer from 0 to 20 mm radius there are no more than 100 microfeatures of a size between 0.002 and 0.008 mm2, no more than 50 microfeatures of a size between 0.008 and 0.018 mm2, no more than 25 microfeatures of a size between 0.018 and 0.05 mm2, and zero microfeatures of a size between 0.05 and 0.1 mm2, and in an outer region of the polycrystalline CVD diamond wafer from 20 to 40 mm radius there are no more than 200 microfeatures of a size between 0.002 and 0.008 mm2, no more than 150 microfeatures of a size between 0.008 and 0.018 mm2, no more than 100 microfeatures of a size between 0.018 and 0.05 mm2, and zero microfeatures of a size between 0.05 and 0.1 mm2. |
