Abstract : In order to provide eye protection for military personnel, two types of laser-protective filter elements were developed for use as inserts in the Goggles, Sun, Wind, and Dust. The elements were designed to be snapped into the goggle frame in back of the standard ballistic lens. A total of 600 Type A filter elements with optical density greater than 4.0 at 400-532 nm and photopic transmission of 44% were delivered to the U.S. Army Natick RD&E Center. These elements met contract requirements with the exception of photopic transmission and resistance to sodium hypochlorite solution. A total of 275 Type B filter elements with optical densities exceeding 4.0 from 694-1064 nm were delivered to Marine Corps Systems Command. These elements measured substantially below the desired 25% minimum photopic transmission, exhibited excessive optical distortion and dye nonuniformity, lost abrasion protection after contact with sodium hypochlorite solution, and lost hardest adhesion after simulated exposure to sunlight.
