Grid-based reticle

Improved target visibility in the area of the primary vertical crosshair

Military Technology

To improve the field of view as well as applicability across various weapons and ammunition, Army scientists and engineers have developed a new reticle for riflescopes and spotting scopes.

In this design, a primary vertical reference crosshair is placed and aligned to the optical axis with its length being less than the maximum field of view. The primary vertical crosshair provides a boresight reference in the optical instrument and axis of symmetry for the grid system.

Advantageously, by locating the primary horizontal crosshair at the top of the grid, otherwise unexpected benefits are realized, including a single concise origin, unobstructed observation of cross range separated or moving targets, and increased utility of the auxiliary horizontal crosshair at higher magnification (which reduces the field of view).

The Army designed this new reticle because current aiming reticle patterns found in riflescopes and spotting scopes issued by the U.S. Army and other armed forces consist of simple intersecting crosshairs with markings consisting of dots or stadia lines at predetermined intervals (one milliradian of angle in target space).

Many sights use a series of secondary crosshairs – patterns that extend the effective coverage area along downward and horizontal directions to allow for corrected aiming references without mechanically adjusting the reticle. However, the high-density markings in at least two of the quadrants formed by the crosshairs can obscure the field of view.

In some commercially available sights, the intervals between markings are caliber specific and different weapon system optics use different reticle patterns. This can, in turn, create issues in training throughout the weapon suite. When the reticle is designed for a specific caliber, any alteration to the standard ammunition may render part of the reticle inaccurate.

Businesses can acquire the patented reticle design for use in new scopes through a patent license. Contact TechLink for no-cost licensing assistance.
