METHOD OF CORRECTION OF DIRECTIONS OF REFLECTED BY PRISM CORNER REFLECTORS OF BEAMS OF PARALLEL LIGHT RAYS Russian patent published in 2018 - IPC G02B5/122 B29D11/00 

FIELD: manufacturing technology; physics.

SUBSTANCE: method can be used in the manufacture of high-precision mirror-prism corner reflectors (CR). Method consists in placing a pinhole in the focal plane of the collimator lens, illuminating the diaphragm and directing a beam of parallel light rays (PLR) to the beam-splitting plate, directing the beam reflected from it to the input face of the CR, which divides the PLR beam into six reflected PLR beams, each of which belongs to one of the six zones of the input face of the CR. Through the beam splitting plate, the PLR beams are directed to the lens, point images from six reflected PLR beams are obtained in its focal plane, and their coordinates are measured with a micrometer. Correction of the directions of the reflected CR of the PLR beams is carried out by applying wedge-shaped layers on three selected zones of the CR input face, having previously selected these zones and having performed the operations of calculating the angles and determining the orientation of the directions of the applied wedge-shaped layers taking into account the required direction of the reflected CR of the PLR beams.

EFFECT: increased reliability and accuracy.
