Abstract
The invention is an improved image intensifier for night vision equipment. It includes an optical filter that is positioned between the phosphor output and eyepiece of the image intensifier. The filter is dichroic and limits light transmission to light that is substantially in the blue wave length. The filter minimizes reflections on the eye of the user that might otherwise be visible to others who are using night vision equipment.
