4Lasers standard uncoated corner cube retroreflectors are fabricated from high-quality UVFS and BK7 optical glasses. Corner cube retroreflector prisms provide beam deviation by 180° and inverted, reversed image independently of angle of incident and operate at large angle of incidence range. Operating principle is based on three total internal reflections inside the prism. To optimize particular application optical transsmision antireflective coatings have to be applied.
