The invention is a dual function laser device for use in night vision
systems. The invention uses lenses to cause one portion of a laser beam to
converge to a target point and another portion of the beam to diverge. The
divergent portion is variable in size and illuminates a viewable area
around the target point. Rather than use two lasers to create an
illuminated view area around an illuminated target point, the invention
uses a combination of a lens and a sub-aperture lens arrangement to create
two illuminations from a single laser.
