10/1/2010 Reducing reflection by up to 100 percent, Steiner’s Anti-Reflective Device (ARD) fits Steiner Porro-prism Military R or Military/Marine binoculars with 30 mm and 50 mm objective lenses. The honeycomb-pattern ARDs are made of non-corrosive parts and use the same Nitrile Butadiene Rubber found on the company’s binocular housings. They attach to the outside of the objective lens barrel, and are held in place by tension fitting adjustable with an included hex key.
