Title (EN) SIGHTING INSTRUMENTS,IN PARTICULAR FOR FIRE ARMS
(FR) INSTRUMENTS DE VISEE, EN PARTICULIER POUR DES ARMES A FEU
Abstract: front page image
(EN)A sight with an optical sighting instrument which includes a lens device with a concave, semi-transparent mirror which is disposed to reflect the image of a light source into the field of view of an eye which is directed towards the concave side of the mirror and observes a target through the lens device. According to the invention, the lens device (1-3), in which the mirror (1) is included, is optically combined with a second lens device (4) which is movably disposed with respect thereto, both lens systems (1-3 and 4) together forming one optical system which is substantially zero-refractive, that is to say neither magnifying nor reducing, and the second lens device is adjustable in two directions which are substantially at right angles to each other and to the major axis (O-F) of the concave mirror surface.
(FR)Viseur avec instrument de visee optique comprenant un dispositif a lentille avec un miroir concave semi-transparent dispose pour reflechir l"image d"une source lumineuse dans le champ de vision d"un oeil qui est dirige vers la face concave du miroir et observe une cible au travers du dispositif a lentille. Ce dispositif a lentille (1-3), dans lequel est incorpore le miroir (1), est combine optiquement avec un second dispositif a lentille (4) qui est mobile par rapport a celui-ci, les deux systemes a lentille (1-3 et 4) formant ensemble un systeme optique de refraction nulle, c"est-a-dire qui ne grossit pas et ne reduit pas, le second dispositif a lentille etant reglable suivant deux directions sensiblement orthogonales entre elles et par rapport a l"axe principal (0-F) de la surface concave du miroir.
