Abstract:
Provided is an illuminated dot reticle for use in a rifle scope (10) having an optical path (16) defined through axially spaced-apart objective (12) and ocular lenses (14) and method manufacturing a reticle disc assembly (24). A reticle disc (26) has a first surface facing the objective lens (12) and a second surface facing the ocular lens (14). A first reticle pattern (32), including a central aiming point (40), is applied to one of the reticle disc surfaces (26). An optical fiber (34) has a proximal end (44) portion and a distal end (36), with a light source (52) configured to deliver light to the proximal end (44) portion of the optical fiber (34). The optical fiber (34) is secured to one of the reticle plate surfaces (28) such that the distal end (36) is positioned to transmit light from the light source (52) toward the ocular lens (14) in the optical path (16), providing an illuminated dot at the central aiming point (40).
