The excellent performance in broad-band optical transparency (except the very small (about 12.4cm^-1) diamond characteristic absorption peak located at 4-6μm) , high thermal conductivity, extraordinary high hardness and high fracture toughness, and very low thermal expansion coefficient make diamond an ideal choice for highly demanding window applications such as high-power IR laser windows, high-power microwave windows to be - used in extreme harsh working conditions.

Large size high quality optical windows can be prepared by our company by both DC Arc Plasma Jet and high power microwave plasma CVD at high pressures, which can benefit you in the following fields:
·Exceptional broad band infrared transparency

·Excellent transparency in the optical and ultraviolet spectrum
·Excellent thermal conductivity
·Low scattering in infrared
·High fracture strength
·Extreme low thermal expansion coefficient
·Can achieve ultra-high-vacuum mounting

We now provide:
