Abstract:

Plastic goggles were produced which offer protection against several lasers. The goggles have a minimum optical density of at least 3 at 0.3-0.4, 0. 84, 0.78-1.76 and 2.755 to 14.0 microns and at least 4 at 1.06 microns. Cast plastic sheet was prepared which had similar protective capabilities. Over 300 organic compounds were evaluated andor synthesized as possible near infrared absorbing compounds. Several of these structural systems offer promise for laser protection. The compounds were evaluated in a variety of plastics including cellulose propionate, polymethyl methacrylate, polycarbonate, polyethylene terephthalate, and polyvinyl chloride. The propionate and methacrylate were the polymers of choice for most of the work. Cadmium stannate was investigated as an absorber and was shown to have some interesting spectral properties. A DISCUSSION IS PRESENTED ON THE CORRELATION BETWEEN STRUCTURE AND SPECTRAL PROPERTIES OF SEVERAL OF THE COMPOUNDS STUDIED.
