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