ABSTRACT:
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).
