<p>A multi-function day/night observation, ranging and sighting device includes a single objective lens (28) and a single eyepiece lens (30) and provides an image of a screen via the light beam (28a). The objective lens leads to a visible-light first optical path and to an invisible-light second optical path. The invisible-light second optical path includes an image intensifier tube for providing a visible image. The first and second optical paths converge with visible images provided by each pathway being overlaid at a reticule plane. A laser provides a pulse of laser light projected into the screen via the single objective lens.</p> |
