Corner Cube Prisms

Corner Cube Prism, also known as Retroreflector or Trihedral Prism, consists of three perpendicular reflecting surfaces resembling the side walls of a cube. The input surface is positioned at a right angle to the diagonal of the cube. Regardless of the angle of incidence, the output beam runs parallel to its input counterpart but in an opposite direction. To ensure better matching among several corner prisms, their entrance-exit surface is often hexagonal-shaped. This phenomenon applies to this particular prism.

Note for Corner Cube Retroreflector


  • Besides N-BK7, custom-made corner cube Prisms made of other optical materials are available.

  • Corner Cube Prisms with lower deviation tolerance, such as 1’, 30”, or 10″,  are available.

  • Corner Cube Prisms with better surface Quality (better than 40/20 or 20/10) are available.

  • HR or Metal reflection coating(Al, Ag, Cu, etc.) on reflection surfaces is available.

  • AR coating on input/output surface is available upon request.

  • Custom-made non-standard Corner Cube Prisms at any other size are available upon request.
