Methods and Systems for Concealing Light

Abstract

A device for preventing secondary light emitted by a laser sight from being seen is disclosed. The device includes a cavity defined by a sidewall and first and second ends of a light containment structure. In some embodiments, the light containment structure is mountable so as to receive light from a laser sight of a weapon through a first opening located at the first end of the light containment structure. The device can include a first portion located at the second end of the light containment structure, and a second opening defined by the first portion and that can pass light from the cavity toward an object such that the object is illuminated to a user of the weapon by the light from the second opening. In some embodiments, the cavity can be configured such that light does not directly illuminate the sidewall.

1 . A device for preventing secondary light emitted by a laser sight from being seen, the device comprising:
 a cavity defined by a sidewall and first and second ends of a light containment structure, wherein the light containment structure is configured to be mounted so as to receive a beam of light from a laser sight of a weapon through a first opening located at the first end of the light containment structure;   a first element located at the second end of the light containment structure; and   a second opening defined by the first element and configured to pass light from the cavity toward an object such that the object is illuminated to a user of the weapon by the light from the second opening;   a second element located between the first opening and the second opening, wherein the second element defines a third opening, and wherein the second element divides the cavity into a first cavity located between the first opening and the second element and a second cavity located between the second element and the first element,   wherein the second cavity is configured such that light from the first opening does not directly illuminate the sidewall,   wherein the beam as a beam cross-sectional area in a beam plane perpendicular to the beam, wherein the first opening has an opening cross-sectional area in a opening plane parallel to the beam plane, and wherein the beam cross-sectional area is greater than the opening cross-sectional area of the first opening.   
     
     
         2 . (canceled) 
     
     
         3 . The device of  claim 1 , wherein the second element is configured to prevent light from the laser sight from directly illuminating the sidewall of the second cavity.
