A night vision device comprising a facemask housing assembly having a peripheral surface defined by a rear surface contoured to a user's face and an open front surface, the housing assembly operative for encasing a pair of optical assemblies operative for receiving light from a viewed object via a first folded optical path and via a second direct optical path, combining the light from the first and second paths, and directing the combined light to a user's eye for viewing the object; where each optical assembly detachably coupled to the housing assembly. 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.
