CA 2413743

The invention relates to an especially monocular night-vision device comprising a lens (11) and lens systems (53, 57, 77) which project the light strengthened by means of a residual light amplifier (33) in a pre-determined wave range, onto a receptor lying on a receiving beam axis (9), such as a human eye (99). Reflective elements (13, 35, 75, 97) bend the beam path of the light through the night-vision device. The reflecting surfaces of at least one pair of the reflective elements (35, 75) are oriented in a coplanar manner. At least one optical component (33, 53, 55, 57, 77) is provided between at least one pair of the four reflective elements (13, 35, 75, 97).

L'invention concerne un dispositif de vigilance nocturne, notamment monoculaire, présentant un objectif (11) et des systèmes de lentilles (53, 57, 77) qui projettent la lumière amplifiée dans une gamme d'ondes prédéterminée par un amplificateur de lumière résiduelle (33) sur un récepteur comme un oeil humain (99) placé sur un axe de faisceau de récepteur (9). Les éléments réfléchissants (13, 35, 75, 97) plient la trajectoire du faisceau de lumière traversant le dispositif de vigilance nocturne. Les surfaces miroir d'au moins une paire d'éléments réfléchissants (35, 75) sont à orientation coplanaire. Au moins un composant optique (33, 53, 55, 57, 77) est placé entre au moins une paire des quatre éléments réfléchissants (13, 35, 75, 97).
