  • Patent number: 9212866
    Abstract: The invention is an Optical Diffraction Alignment Lens, incorporating a symmetric planar-array of pin-hole apertures, installed in a split bowstring configuration replacing the conventional peep sight on a tuned compound bow with a front sight fiber optic pin, providing to the archer a virtual aperture through the fiber optic pin tip as a precise alignment and aiming system for the arrow flight path to target. The Optical Diffraction Alignment Lens, the center of which is positioned in the vertical plane centered on the arrow flight path and fixed relative to the arrow nock end, presents to the aiming eye of the archer, a well-defined virtual aperture image in the tip of the front fiber optic pin, as a centered point of alignment, that is centered by the archer in the line-of-sight which the archer aligns through the virtual aperture to the impact point on target.
