US12529542 - Optical sighting device

An optical sighting device 10 used by being installed to a firearm includes: an objective system part 12 , forming an inverted image of a target object on a first focal plane; and an erect system part 14 , forming an erect image obtained by reversing the inverted image on a second focal plane. The erect system 14 has: lenses 112 to 116 arranged between the first focal plane and the second focal plane; and a movable cylinder 134 as an erect system cylinder holding the lenses 112 to 116 . The adjustment mechanism 20 is a mechanism for adjusting tilting of an axial direction of the movable cylinder, and has: an advancing-retracting shaft 204 as an advancing-retracting member advancing and retracting on an end side of the movable cylinder 134 ; and a spring 206 as a double torsion spring biasing the movable cylinder 134 toward the advancing-retracting shaft 204.

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.
