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.
Claims23
A sight for a firearm having a barrel, the sight comprising:
- a spool;
- a sight post extending from the spool;
- a mounting base connected to the spool for connecting the sight to the barrel;
- an elongate light collector having opposite ends, at least one end thereof connected to the sight post, the at least one end defining at least one rearwardly facing sight point for viewing by a user, the light collector being formed such that light can be gathered along its length and transmitted to the at least one end;
- the light collector further comprising:
- an axial section extending from the sight point and connected to the sight post;
- a curved transition section optically coupled with the axial section, the curved transition section having a radius of curvature that is sufficiently large to substantially reduce or eliminate light loss from the light collector and thereby increase a brightness of the sight point;
- and
- a coiled section extending from the curved section and spiraling around the spool.
A sight for a projectile launching device, the sight comprising:
- a spool;
- a sight post extending from the spool;
- an elongate light collector having opposite ends, at least one end thereof connected to the sight post, the at least one end defining at least one rearwardly facing sight point for viewing by a user, the light collector being formed such that light can be gathered along its length and transmitted to the at least one end;
- the light collector further comprising:
- a curved transition section optically coupled with the rearwardly facing sight point, the curved transition section having a radius of curvature that is sufficiently large to substantially reduce or eliminate light loss from the light collector and thereby increase a brightness of the sight point;
- and
- a coiled section extending from the curved section and spiraling around the spool.
