The invention relates to a compact night observation viewer (Fig. 1) with one light amplifier (1) and amongst others two eyepieces (13A/B) in the horizontal plane under the input aperture (20), and where one eyepiece (13A) can be folded out of the beam path (Fig. 3) so that a free through-view passage is opened through the viewer, whereby the observed scene can also be observed without light amplification. The invention solves thereby the problem of how in a technically and economically satisfactory way it is able to freely change between binocular and monocular vision. As an addition and optionally, the invention permits the distance between the two eyepieces to become adjustable and that a teleconverter (Fig. 3) can be applied in front of the light amplifier input (20) and possibly also in above described free through-view opening so that magnification can be switched (Fig. 4) both with and without light amplification. |
