Abstract
A weapon sight has an optical system that causes first radiation to propagate along a path of travel within the sight, and has a reticle generating portion that causes second radiation representing a reticle to propagate along the path of travel with the first radiation. The reticle generating portion includes a reticle illuminating portion that illuminates the reticle. The reticle illuminating portion includes a first light source having thereon a surface, light from the first light source passing through the surface and then illuminating the reticle. The reticle illuminating portion also includes a second light source spaced from the first light source, light from the second light source traveling toward the surface, being reflected and then illuminating the reticle.
