PCT No. PCT/SE84/00254 Sec. 371 Date Mar. 5, 1985 Sec. 102(e) Date Mar. 5, 1985 PCT Filed Jul. 6, 1984 PCT Pub. No. WO85/00433 PCT Pub. Date Jan. 31, 1985.A night vision instrument with an electronic image converter, comprising for example an image intensifier tube or a similar device. This night vision instrument (FIG. 3) may be located beside an ordinary telescope, sight, TV-camera or similar device (6) so that this same device may be used during night time. The combined system (FIG. 3) thus arranged is very compact, with the center of gravity close to the user during handheld operation. The lightgathering objective lens consists moreover of only one mirror (1) and the image emerging on the screen (3) of the electronic image converter is facing the corresponding object being viewed. The image on the screen (3) is finally collimated so that it may pass into the entrance aperture of some other instrument (6) in parallel, and this image transfer is accomplished with three reflections or less and without any intermediate real image. |
