  • Laser radiation barrier
    Patent number: 5306373
    Abstract: An apparatus and method is disclosed for an improved laser radiation barrier for shielding a surface from laser radiation comprising an outer polymeric layer comprising a dispersion of mica, an intermediate mica layer for retarding the penetration of the laser radiation therethrough and an inner polymeric layer comprising a dispersion of mica bounded to the intermediate mica layer. The polymeric layers comprises a dispersion of titanium dioxide. An optical metallic barrier may be interposed between the outer polymeric layer and the intermediate mica layer for distributing thermal energy.
    Type: Grant
