  • OPTICAL QUALITY DIAMOND MATERIAL
    Publication number: 20210115591
    Abstract: A CVD single crystal diamond material suitable for use in, or as, an optical device or element. It is suitable for use in a wide range of optical applications such as, for example, optical windows, laser windows, optical reflectors, optical refractors and gratings, and etalons. The CVD diamond material is produced by a CVD method in the presence of a controlled low level of nitrogen to control the development of crystal defects and thus achieve a diamond material having key characteristics for optical applications.
    Type: Application
    Filed: October 27, 2020
    Publication date: April 22, 2021
    Applicant: ELEMENT SIX TECHNOLOGIES LIMITED
