Corner Cubes / Solid Retro Reflectors (CCP)

Home Prisms  Corner Cubes / Solid Retro Reflectors (CCP)

  • 180° bending prisms
  • 2 dimensional constant deviation
  • Total internal reflection at three faces

Corner cubes are excellent retro-reflectors. They return an incoming beam in the opposite direction along the same path. They produce a two dimensional 180° beam deviation making them useful for alignment purposes. These prisms are manufactured from BK7A or Fused Silica and may be selected to have 2, 5 or 10 arc sec angular deviation tolerance. The prisms are supplied uncoated but Lambda can apply anti-reflection coatings to the entrance face and protected metallic coatings to the three cube corner faces as required.
