Each optical assembly comprises an objective lens assembly for receiving and focusing visible and infrared light from a viewed object along the first folded optical path; image intensifier means responsive to the focused light from the objective lens assembly for converting the visible and infrared light to visible intensified light; and beam combining means responsive to the visible intensified light and to the direct path light for combining with one another and directing the combination to the user's eye for viewing.
