<p>A phosphorescent or light-reflective member (28, 36) is disposed on a holder (18, 42, 44) supporting an elongated light-gathering optical fiber (20) formed of a light-gathering fluorescent plastic material. The sight (10) is adaptable for use on rifles, handguns, bows, and other weapons requiring an aiming indicia. The light-gathering fluorescent optical provides a brilliant dot that is readily identifiable under bright light conditions, and the phosphorescent or light-reflecting member provides a supplemental light source which serves to provide an illuminated dot under low-light or dark conditions. The sight (10) effectively solves the problem of providing electrically-powered light sources for illumination of the aiming indicia under low light or dark conditions, or the requirement to precisely align the fiber or hollow tube with a light source disposed at the distal end of the fiber or tube spaced from the viewing end of the fiber or tube.</p> |
