    CVD Blanks For Optical Windows

    Introduction:

    CVD (Chemical Vapor Deposition) Diamond is a mixture of carbon-containing gas and hydrogen at high temperatures and sub-standard atmospheric pressure is excited to decompose to form an active Diamond carbon atoms and deposited on the substrate intergrowth of polycrystalline Diamond.Since CVD Diamond does not contain any metal catalyst, so its thermal stability close to natural Diamond.CVD Diamond grains are disordered, non-brittle cleavage plane, thus showing isotropic.CVD Diamond is widely used in mechanical, microelectronics, thermal, optical, Aerospace, Military, Medical and other fields.Our company mainly produces the following types of CVD Diamond products: CVD Diamond wire drawing die core, CVD Diamond dresser blank, CVD Diamond cutter blank, thermal grade CVD Diamond sheet, optical grade CVD Diamond sheet and other multi-grade CVD products.And can be cut according to user requirements, polishing and other processing.

     

    Product introduction:

    Our CVD Diamond optical sheet has excellent optical properties, mechanical properties and thermal properties;from X-rays, ultraviolet light, visible light, infrared light up to millimeter Microwave band has a high transmittance, excellent mechanical properties and thermal properties, so that it can be used in harsh environments.
