PCT No. PCT/SR96/01323 Sec. 371 Date Jun. 22, 1998 Sec. 102(e) Date Jun. 22, 1998 PCT Filed Oct. 31, 1996 PCT Pub. No. WO98/19199 PCT Pub. Date May 7, 1998A compact night observation viewer has one light amplifier and two eyepieces in the horizontal plane under the input aperture, and where one eyepiece can be folded out of the beam path 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 can be applied in front of the light amplifier input and possibly also in above described free through-view opening so that magnification can be switched both with and without light amplification.
