Photograph of  design structure of the Optical Diffraction Alignment Lens (patent pending) incorporated in SNYPRalignment

The Optical Diffraction Alignment Lens (patent pending) embodies a symmetric planar array of  pinhole apertures that create a virtual image through the center of the lens and through the center of the fiber optic tip in the front sight.  This provides a virtual image presented to the aiming eye of the archer when at full draw of the arrow and aimed at the target along the unobstructed view directly to the intended impact point on target as shown in the target image below.
