Improved reflex sight having a frequency selective collimating beam combining mirror

Claim 2

An improved reflex sight having an enclosing member, a front window, and a rear window and comprising in combination: light conducting reticle indicia adapted to be directly illuminated by incident light; frequency selective beam combining collimating means comprising a portion of said front window and adapted to simultaneously provide a collimated image of said reticle indicia and an uncollimated view of a target; reflective means comprising a portion of said rear window and so positioned with respect to said frequency selective beam combining collimating means as to allow said incident light to be light emanating from the general area of said target; and frequency selective light passing means positioned in front of said front window and adapted to substantially eliminate any down range reflections of light off of said front window.

Claim 5

An enclosed reflex sight for providing a reticle indicia image the brightness of which varies directly with target brightness and having an enclosing member which supports a front window and a rear window and comprising: light conducting reticle indicia adapted to be directly illuminated by incident light passing through a first portion of said front window from the general area of the target; means associated with said rear window for deviating the light passing through said indicia to direct said light back toward a second portion of said front window; frequency selective beam combining collimating means associated with said second portion of said front window and adapted to simultaneously provide a collimated image of said reticle indicia predominantly of a first portion of the target area light spectrum and an uncollimated view of the target predominantly of a second portion of the target area light spectrum; and a forwardly protruding portion associated with said enclosing member and provided with a light absorbing low reflectance surface which is oriented with respect to said frequency selective beam combining collimating means so as to prevent light being reflected toward said target.

Claim 6

An enclosed reflex sight for providing a reticle indicia image the brightness of which varies directly with target brightness and having an enclosing member which supports a front window and a rear window and comprising: light conducting reticle indicia adapted to be directly illuminated by incident light passing through a first portion of said front window from the general area of the target; means associated with said rear window for deviating the light passing through said indicia to direct said light back toward a second portion of said front window; frequency selective beam combining collimating means associated with said second portion of said front window and adapted to simultaneously provide a collimated image of said reticle indicia predominantly of a first portion of the target area light spectrum and an uncollimated view of the target predominantly of a second portion of the target area light spectrum; and a forwardly protruding portion associated with said enclosing member and provided with a light absorbing low reflectance surface which is oriented with respect to said frequency selective beam combining collimating means so as to prevent light being reflected toward said target.

Claim 7

An enclosed reflex sight for providing a reticle indicia image the brightness of which varies directly with target brightness and having an enclosing member which supports a front window and a rear window and comprising: light conducting reticle indicia adapted to be directly illuminated by incident light passing through a first portion of said front window from the general area of the target; means associated with said rear window for deviating the light passing through said indicia to direct said light back toward a second portion of said front window; frequency selective beam combining collimating means associated with said second portion of said front window and adapted to simultaneously provide a collimated image of said reticle indicia predominantly of a first portion of the target area light spectrum and an uncollimated view of the target predominantly of a second portion of the target area light spectrum; and a reflection suppressing window supported by said enclosing member and having an interference coating thereon, said reflection suppressing window being aligned with said front and rear windows and inclined with respect to a line of sight through said front and rear windows so as to prevent reflection in the direction of said line of sight toward the target.

Claim 8

An enclosed reflex sight for providing a reticle indicia image the brightness of which varies directly with target brightness and having an enclosing member which supports a front window and a rear window and comprising: light conducting reticle indicia adapted to be directly illuminated by incident light passing through a first portion of said front window from the general area of the target; means associated with said rear window for deviating the light passing through said indicia to direct said light back toward a second portion of said front window; frequency selective beam combining collimating means associated with said second portion of said front window and adapted to simultaneously provide a collimated image of said reticle indicia predominantly of a first portion of the target area light spectrum and an uncollimated view of the target predominantly of a second portion of the target area light spectrum; and a reflection suppressing window supported by said enclosing member and having an interference coating thereon, said reflection suppressing window being aligned with said front and rear windows and inclined with respect to a line of sight through said front and rear windows so as to prevent reflection in the direction of said line of sight toward the target.

Claim 9

An enclosed reflex sight for providing a reticle indicia image the brightness of which varies with the brightness of a target being viewed comprising: light transmitting reticle indicia on an otherwise opaque background adapted to pass incident light from the target area; frequency selective beam combining means adapted to superimpose a collimated image of said reticle indicia predominantly of a first portion of the target area light spectrum and an uncollimated view of the target predominantly of a second portion of the target area light spectrum; and means provided with a light absorbing low reflectance surface and extending from said frequency selective beam combining means in the general directional of the line of sight to the target a distance sufficient that any line normal to said beam combining means will intersect said surface so as to prevent incident light being reflected toward the target by said frequency selective beam combining means.

Claim 10

An enclosed reflex sight for providing a reticle indicia image the brightness of which varies with the brightness of a target being viewed comprising: light transmitting reticle indicia on an otherwise opaque background adapted to pass incident light from the target area; frequency selective beam combining means adapted to superimpose a collimated image of said reticle indicia predominantly of a first portion of the target area light spectrum and an uncollimated view of the target predominantly of a second portion of the target area light spectrum; and means provided with a light absorbing low reflectance surface and extending from said frequency selective beam combining means in the general directional of the line of sight to the target a distance sufficient that any line normal to said beam combining means will intersect said surface so as to prevent incident light being reflected toward the target by said frequency selective beam combining means.
