Abstract
An illuminated sighting device includes an elongate light collector having one end defining a sight point that faces rearwardly for viewing by a user. The light collector is formed such that light can be gathered along its length and transmitted to the one end. The light collector further includes a curved transition section optically coupled with the sight point. The curved transition section has a radius of curvature that is sufficiently large to substantially reduce or eliminate light loss from the curved section and thereby increase a brightness of the sight point.
