Abstract
The present invention provides for photoluminescent optical fibers that are used to illuminate sighting reticles. The fibers are activated by electromagnetic radiation and emit electromagnetic radiation of various wavelengths at high intensity and for long periods of time. The emission from the photoluminescent fiber can only be seen coming from one terminal end of the fiber, which is designed to be positioned inside the sighting device to illuminate a reticle. The photoluminescent fiber contains a base optical fiber which is covered at least in part by a photoluminescent composition which itself is fully covered by a second composition that allows the activating electromagnetic radiation to pass through to activate the photoluminescent layer while preventing the emissive electromagnetic radiation of the photoluminescent layer from passing back through.
