Abstract:
An optical aiming device including a first multi-faceted optical element lying on an axis and a second multi-faceted optical element juxtaposed to the first multi-faceted optical element and angled with respect thereto, the first and second optical elements each being characterized by a refractive index and a critical angle defining at least one total internal reflection plane formed by at least one facet of each one of the first and second optical elements, the at least one facet having an optical interference coating formed thereon, each one of the first and second optical elements causing light impinging on the at least one total internal reflection plane at an angle greater than or equal to the critical angle to be totally reflected and light impinging on the at least one total internal reflection plane at an angle less than the critical angle to be partially reflected and partially refracted, the totally reflected light illuminating a first region, the partially reflected light partially illuminating a second region, a demarcation being defined between the first and second regions, the first and second optical elements being oriented such that the demarcations of the first and second optical elements intersect at a point lying substantially along the axis.
