Measuring Devices -Corner Cube Retroreflector for Silver Survey Spectroscopy Highlights Generic Brand Corner Cube Retroreflector for Silver Survey Spectroscopy Description: Corner cube retroreflector, also known as CCR prism or trihedral prism, manufactured from BK7 thin optical glass The typical corner cube design reflects incident light at 180 degrees. Some applications require the reflected ray to return at a different angle. A number of coating options are available for corner cube retroreflectors. An anti-reflective (AR) coating can be applied to the front face, and the three reflective faces can be coated with a metallic or dielectric coating, or can remain uncoated. Corner cubes are used in a wide variety of applications such as spectroscopy, laser resonator cavities, surveying, ground range finders, satellite communications, and space vehicle docking.
