Corner Cube Prisms
Retro-reflection to 5 arc sec

Corner Cube Prisms or retroreflectors have the property that any ray entering the effective aperture will be reflected back parallel to itself, regardless of the entrance angle. The incident beam filling the effective aperture is reflected back on itself. These retroreflectors are ideal in applications where orientation is difficult or impossible to control

Beam Deflection: 180 degree more or less 5"
Material: BK7 optical glass, fine annealed
Dimension: More or less 0.15mm
Wavefront Distortion: ∧/8
Surface Quality: 20-10 scratch-dig
Coatings: AR anti-reflection film for entrance faces. The reflection face is aluminum coated with black white paint for protection.
