Transmission Windows

Diamond’s exceptional transparency covers the visible, infrared, terahertz and microwave regions making an ideal material choice for multi-spectral applications including synchrotron beam and microwave transmission lines. Some examples of successful applications:

  • Diamond exit windows for high power IR laser systems maintain beam quality and laser focus position by eliminating the formation of a thermal lens.
  • In the terahertz region, diamond has no absorption bands and a constant refractive dispersion with wavelength. Space-based systems benefit when performing space bound astronomical spectroscopy and infrared atmospheric analysis.
  • Microwave beams with power levels exceeding 1 MW are generated by high-power gyrotron tubes. To be capable of handling these high power densities, windows for these tubes and other components of microwave transmission lines are often made of diamond.
