also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam's angle of entry.
Corner cube, also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam’s angle of entry. Its three reflecting surfaces are erpendicular each to the other (like side walls of a cube) . For applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces can not be kept sufficiently clean for TIR, a metal or dielectric coating can be applied to the reflecting surface .This prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.
