Persistent Illuminators as a Replacement for Tritium in Weapons Sights

Illuminated weapons sights provide an enhanced capability to acquire and engage targets, particularly in low-light levels. Currently, tritium is used exclusively as a persistent, non-electric source of illumination in military sights because of its simplicity and low weight. However, tritium presents numerous safety concerns and logistic problems due to its radioactivity. Storage, transportation, and disposal of tritium sources are expensive and burdensome, resulting in measurable legacy costs. A persistent, non-electric, non-radioactive method of illuminating weapons sights is available to replace tritium while retaining the current capability. Our revolutionary photoluminescent (PL) technology is that alternative.
