Abstract:
1. A binocular comprising: a first barrel, containing a first optics system having a first objective lens system, wherein said first objective lens system contains a first plurality of objective lenses, a first set of at least two pairs of prisms, a first ocular lens system, wherein said first ocular lens system comprises a first plurality of ocular lenses, further wherein an image received by said first ocular lens system is less than one focal length away from said first objective lens resulting in the production of a magnified image, and being configured to provide a first higher powered magnification which presents a detailed image in a first field of view defined by central image produced by the first optics system; a second barrel operatively attached to the first barrel said second barrel containing a second optics system having a second objective lens system, wherein said second objective lens system comprises a second plurality of objective lenses, a second set of at least two pairs of prisms, a second ocular lens system, wherein said second objective lens system comprises a second plurality of ocular lenses, further wherein an image received by said second ocular lens system is less than one focal length away from said second objective lens resulting in the production of a magnified image, and being configured to provide a second lower powered magnification which presents an image of a surrounding environment of said detailed image in a second field of view, said second magnification being less than said first magnification; and a reticle in the second barrel corresponding to said first field of view as it appears in the said second barrel, so that the reticle matches the view of said first field of view as it is presented in the second barrel, wherein the second barrel has at least one set of prisms, wherein said second field of view is greater than said first field of view,
