Abstract: An interface facility has a first facility element connected to an ocular, a device case configured to connect to a smart device, a second facility element connected to the device case, the first and second facility elements being configured to connect to each other in a connected condition and to detach from each other, the first facility element being registered with a first optical axis associated with the ocular, the second facility element being registered with a second optical axis associated with the camera, the first and second optical axes being registered with each other when the first and second facility elements are in the connected condition, such that the camera records images generated by the ocular. The first and second facility elements may comprise a bayonet mount.

Abstract: An optic assembly may include: an environmentally isolated cavity defined by at least a front lens and a housing; a light source located inside the environmentally isolated cavity, the light source to project a reticle on the front lens; and a carrier assembly located inside the environmentally isolated cavity, wherein the light source is mounted on a carrier of the carrier assembly, and the carrier assembly includes: at least one boss fixably located with respect to a bottom interior surface of the environmentally isolated cavity; and a carrier lift slidingly movable along the at least one boss to raise or lower the light source relative to the front lens; wherein the carrier is slidably movable relative to the carrier lift to laterally adjust a position of the light source relative to the front lens. Other embodiments may be disclosed and/or claimed.

Abstract: A reflex sight with multiple aiming marks has a body having a forward end extending in forward direction and an opposed rearward end extending in a rearward direction, a first optical element having a first concave surface facing in the rearward direction, the first concave surface having a first focal point, a second optical element having a second concave surface facing in the rearward direction, the second concave surface having a second focal point, a first emitter proximate the first focal point and spaced apart from the second focal point, a second emitter proximate the second focal point and spaced apart from the first focal point, and the first optical element being forward of the second optical element. The first and second emitters may both be rearward of the first and second optical elements. The second emitter may be spaced apart rearwardly from the first emitter.
