Enhanced night vision device
First Claim
1. 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, said housing assembly operative for encasing a pair of optical assemblies, said optical assemblies operative for receiving light from a viewed object via a first folded optical path and via a second direct optical path, combining said light from said first and second paths, and directing said combined light to a user'"'"'s eye for viewing said object;
each said optical assembly detachably coupled to said housing assembly, wherein each optical assembly comprises;
an objective lens assembly for receiving and focusing visible and infrared light from a viewed object along said first folded optical path;
image intensifier means responsive to said focused light from said objective lens assembly for converting the visible and infrared light to visible intensified light;
and beam combining means responsive to said visible intensified light and to said direct path light for combining with one another and directing the combination to said user'"'"'s eye for viewing.

Abstract
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.
