Abstract

A Blue-Green spectral Filter and two polaroid filters are assembled within rotating barrel assembly to both limit light source emissions to a selected light spectrum and control light intensity in order to prevent enemy night vision device detection. The rotating barrel assembly can be manufactured to attach to any type of light source. In addition, environmental protection from rain and dust is maintained through O-ring seals.
