Abstract
A day/night sight includes a visible-light first optical path and an invisible-light second optical path which are everywhere optically coaxial. The invisible-light second optical path leads to a detector or to an image intensifier tube for providing either an electrical signal or a visible image, respectively, in response to the invisible-light image. A third optical path for the visible image from the image intensifier tube is also everywhere optically coaxial with the first and second optical paths. A visible image produced from the electrical signal is introduced into the first optical path to thereafter be coaxial therewith. Consequently, a uniquely compact arrangement of the elements for the day/night sight is achieved.
