Abstract
A reflective sighting device includes a reflective sight component having a reflective surface for facing a user and a light source arranged for projecting a reflected image onto the reflective sight component for view by the user along a line of sight. A first focal plane of the reflected image is closer to the reflective sight component than a second focal plane of a distant target, so that movement of the reflected image is minimized as perceived by a viewer when the reflective sighting device is subjected to small unwanted movement.
