Abstract

La présente invention concerne un dispositif téléscopique (1) conçu pour la vision bifocale, et comportant: un système optique permettant une observation de type champ de vision; un carter servant à renfermer et maintenir en place le système optique, à savoir, d'une part une lentille (3) d'objectif située sur l'une des extrémités du carter et caractérisée par un premier axe (X) optique, et d'autre part une lentille (4) d'oculaire située sur l'extrémité opposée du carter et caractérisée par un second axe (X') optique; un système comprenant des éléments optiques réfléchissants et/ou réfringents et/ou diffringents destinés à incliner le premier axe optique par rapport au second axe optique de façon à permettre l'observation simultanée d'une cible et de son image agrandie. L'ensemble comporte enfin un organe (11) d'acquisition de la cible.
