Abstract
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.
