Naturally illuminated optical reflex sighting system for firearms
The patent US11976901B2 describes a naturally illuminated optical reflex sighting system designed for firearms. This system features a housing that can be detachably mounted to a firearm and includes multiple light collection and transmission windows. Central to the design is a fiber optic element that absorbs ambient light and generates a reticle on a lens for aiming. The housing is structured to create an upwardly open light-gathering cavity that accommodates a coiled section of the fiber optic element, which is enclosed by a light-transmissible cover. This cover is made from transparent polymer or glass and is designed to facilitate the collection and transmission of ambient light through the windows to the fiber optic element.
The sighting system is notable for its lack of artificial light sources, relying solely on natural ambient light to illuminate the reticle. The configuration includes a front window, lateral side windows, and an upwardly open top window, all of which enhance light exposure to the fiber optic element. The design also incorporates a guide channel within the cover to manage the light-emitting end section of the fiber optic element, ensuring efficient light transmission to the lens. The reticle's intensity can vary based on the available ambient light, making this sighting system adaptable to different lighting conditions. Overall, the invention presents a novel approach to firearm optics by utilizing passive illumination techniques.
