Standard specifications

4Lasers standard uncoated corner cube retroreflectors are fabricated from high-quality UVFS and BK7 optical glasses. Corner cube retroreflector prisms provide the beam deviation by 180° and create an inverted, reversed image independent of the angle of incidence, with a wide incident angle acceptance range. The operating principle is based on three total internal reflections inside the prism. Antireflective coatings have to be applied in order to optimize the optical transmission for a particular application. Contact us for coating service, custom solutions, and pricing.
