US12345504 - Dual band gun-sight calibrator

The patent describes a dual band gun-sight calibrator that allows for dry zeroing of both daylight and thermal gun-sights using a specialized focusing assembly. This assembly features a lens and a switching mechanism to toggle between sighting configurations, with a zeroing target that includes a reticle designed to be opaque to visible light and conductive.

Claim 1

1. A zeroing assembly for a gun-sight comprising: a zeroing target; and a dual band focusing assembly, wherein the dual band focusing assembly comprises a lens and a switching mechanism configured to reversibly switch the focusing assembly from a first sighting configuration to a second sighting configuration; wherein the zeroing target includes a reticle made of a material that is opaque to visible light and a good conductor. a zeroing target; and a dual band focusing assembly, wherein the dual band focusing assembly comprises a lens and a switching mechanism configured to reversibly switch the focusing assembly from a first sighting configuration to a second sighting configuration; wherein the zeroing target includes a reticle made of a material that is opaque to visible light and a good conductor.
