Diamond Elements is one of the earliest CVD companies in the world engaged in the manufacturing of single crystal diamond products for a wide range of applications. The microwave plasma chemical vapor deposition method (MPCVD) has been in practical use for 80 years and has become a notable process in the last 7-8 years. MPCVD is a pure and fast diamond deposition process, making it suitable for commercial use. The quality of diamonds grown in the single crystal lab at Diamond Elements is highly stable, with predictable properties and behaviors, and is used in cutting, optical, electronic, and detector applications. 【Features】 ■ MPCVD effectively produces single crystal diamonds (SCD) ■ Development of lab-grown diamond plates suitable for demanding applications ■ CVD plates are available in various dimensions and thicknesses ■ The grown diamond plates provide a very wide spectral range with low absorption coefficients at major laser frequencies and possess very high thermal conductivity *For more details, please refer to the PDF document or feel free to contact us.
