Title (EN) A METHOD OF ARRANGING THE RAY PATH IN AN OPTICAL INSTRUMENT
(FR) METHODE POUR ARRANGER LA TRAJECTOIRE DES RAYONS DANS UN INSTRUMENT OPTIQUE
Abstract: front page image
(EN)The present invention comprises a way to arrange the light path in a monocular, binocular or similar instrument (7), to obtain in practice an instrument as compact and ergonomical as possible, at the same time as best possible optical data are maintained and the internal mirrors (1-4) can be given smallest dimensions. The light path is located near a plane, but at least two (2; 3) of the image erecting mirrors are located on each side of this plane. The light from the objective (6) strikes these two mirrors (2; 3) in turn, and image tilt is eliminated by inclining the intersection line for said two mirrors (2; 3) to the plane.
(FR)L'invention concerne une méthode pour arranger la trajectoire lumineuse dans un instrument monoculaire, binoculaire ou semblable (7) de manière à réaliser un instrument le plus compact et le plus ergonomique possible, tout en maintenant les meilleures données optiques possibles, et en utilisant des miroirs internes (1-4) aux plus petites dimensions. On situe la trajectoire près d'un plan, au moins deux (2, 3) des miroirs pour redresser l'image étant placés de chaque côté dudit plan. La lumière provenant de l'objectif (6) est incidente sur chaque miroir (2, 3) l'un après l'autre, l'inclinaison de l'image étant éliminée en inclinant la ligne d'intersection desdits deux miroirs (2, 3) par rapport au plan.
