Abstract
Disclosed herein are embodiments of a sighting device, and methods of making and using such a sighting device, whereby the sighting device comprises a chamber coupled to the sighting device; and a light-emitting element contained within the chamber; wherein the chamber contains only non-radioactive material; and wherein the light-emitting element emits a first amount of visible light to provide a viewable aiming indicium in low light conditions.
Claims15
A sighting device configured for use with a weapon, comprising:
- a chamber coupled to said sighting device;
- and
- a light-emitting element contained within said chamber;
- wherein said light-emitting element comprises a phosphorescent material loaded within a curable resin to provide a phosphor-loaded resin;
- wherein said phosphorescent material emits a first amount of visible light following exposure to a light source to provide a viewable aiming indicium in low light conditions;
- wherein said phosphorescent material continues to emit said first amount of visible light after discontinuation of exposure to said light source to provide persistent luminescence;
- wherein said phosphorescent material comprises strontium aluminate doped with europium and dysprosium;
- and
- wherein said chamber contains only non-radioactive material.
