US12480742 - Dual illumination optical sight

An optical sight for a firearm can be provided with multiple light sources for illuminating one or more aiming marks on the sight. The light sources may be multiple LEDs, e.g. of different colors that can provide illumination in different lighting conditions. The lights sources may also be physical process driven light sources, such as a Gaseous Tritium Light Source (GTLS). A combination of LEDs and GTLS may also be used. The light sources may be disposed at multiple focal points of a multi-lens system. Alternatively, a selector may be used to selectively locate one of the light sources at the focal point of a single lens system. The optical sight may be a reflex sight, e.g. for a handgun, or may be a riflescope for a rifle.

The patent describes an optical sight for firearms that incorporates multiple light sources, including Gaseous Tritium Light Sources (GTLS) and LEDs, to enhance visibility of aiming marks under various lighting conditions. The design allows for either a multi-lens system or a single lens system with a selector to optimize illumination.

Claim 1

1 . An optical sight for use on a weapon, the optical sight comprising: (A) a housing; (B) an optical system within the housing and comprising at least one lens element, the at least one lens element comprising at least one focal point and at least one aiming mark; (C) a first light source configured to illuminate the at least one aiming mark and comprising at least one Gaseous Tritium Light Source (GTLS) element; and (D) a second light source comprising at least one electric driven light source that is optically coupled to the at least one GTLS element so that a light output of the at least one electric driven light source illuminates the at least one GTLS element to increase the luminance of the at least one GTLS element. (A) a housing; (B) an optical system within the housing and comprising at least one lens element, the at least one lens element comprising at least one focal point and at least one aiming mark; (C) a first light source configured to illuminate the at least one aiming mark and comprising at least one Gaseous Tritium Light Source (GTLS) element; and (D) a second light source comprising at least one electric driven light source that is optically coupled to the at least one GTLS element so that a light output of the at least one electric driven light source illuminates the at least one GTLS element to increase the luminance of the at least one GTLS element.
