Naturally illuminated optical reflex sighting system for firearms
A recently granted patent (Publication Number: US11976901B2) discloses a naturally illuminated optical reflex sighting system for firearms. The system includes a housing with light collection and transmission windows, a lens, a fiber optic element that absorbs ambient light, and a light-transmissible cover that communicates with the windows to transmit light to the fiber optic element. The fiber optic element generates a reticle on the lens for aiming the firearm, with the housing featuring an upwardly open light-gathering cavity that receives a coiled section of the fiber optic element. The reticle's intensity varies based on ambient light, and the system does not rely on artificial light sources for illumination.
Furthermore, the patent describes a firearm equipped with this passively illuminated optical reflex sighting system, featuring a housing with light collection windows, a lens, and a fiber optic element with a light-absorbing circuitous section and a light-emitting end section. The system generates a reticle for aiming the firearm without artificial light sources, with the cover supporting the fiber optic element independently of the housing. The firearm also includes a male dovetail protrusion for attachment to the firearm body and ensures precise alignment. Additionally, a method for providing a firearm with this sighting system is outlined, emphasizing the absorption of natural ambient light through the fiber optic element to create the reticle on the lens. The system's design allows for easy mounting and adjustment, enhancing accuracy and performance for firearm users.
