Method for viewing through reflections from a reflective surface without affecting point of impact

Abstract

Featured is a method and device that minimize the effects of reflections from a transparent surface while viewing an object or target area through such reflective surface and which accomplishes this without affecting the crucially important accuracy of showing where a projectile from a weapon should impact a target. A method for viewing an object from a first side of a transparent medium, the first side being a reflective surface, when the object is located on an opposite side of the transparent medium, includes the steps of providing a telescopic viewing mechanism, mounting a filter at an exit aperture of the viewing mechanism and passing light from the object through the viewing mechanism and through the filter. The filter is configured to significantly attenuate light being reflected from the first side and in a particular embodiment is a polarizing filter. The method further includes filtering the light, being reflected from the first side and passing through the telescopic viewing mechanism, using the filter. In such a method the reticle of the telescopic viewing mechanism is not shifted from the point of impact. Also featured is a method for attenuating light being reflected from a transparent member and an apparatus including a weapon sight or telescopic viewing mechanism and a polarizing filter mounted rearwardly of the weapon sight.
