Diamond Optics

Diamond has an exceptionally high transmission over a very broad range of wavelengths and low scatter in IR applications. It is extremely hard and chemically inert; making CVD diamond the optimal choice in applications demanding higher power, larger area, and resistance to hazardous materials or greater strength.  These abilities also enable smaller material geometries to be used, which opens up new lightweight applications.  Advances in the creation and shaping of diamond enable us to provide solutions to novel optical problems.

CVD Optical Transmission

Applied Diamond’s optical products are:

  • Available in both SC (up to 7.5 mm sq) and poly (up to 2” in diameter)— Thicknesses up to 1.2 mm
  • Surface roughness down to 2-3 nm Ra for SC and 10 nm Ra for poly
  • Wedged or flat—wedged for the suppression of interference oscillations. Wedge angle: 0.5 to 1 degree
  • Mounted in flange or free-standing
  • Cut in a variety of shapes and sizes, including lenses and prisms
  • Up to 30 mm free aperture for brazed windows—leak tight at better 1 x 10E-10 atm-cc/sec
