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.
