  • Patent number: 5953165
    Abstract: An optical aiming device including two optical elements, each characterized by a refractive index and a critical angle defining a total internal reflection plane, positioned one in front of the other substantially along an aiming axis, each optical element causing a portion of light impinging thereon at an angle greater than the critical angle, to be reflected, thereby defining a demarcation between a region of reflected light and non-reflected light, the optical elements being oriented such that the demarcations of each optical element intersect at a point lying substantially along the aiming axis.
