Title (EN) LAYERED, COMPOSITE LENS AND METHODS OF CONSTRUCTION
(FR) LENTILLE COMPOSITE STRATIFIÉE ET PROCÉDÉS DE CONSTRUCTION
Abstract:
(EN) A protective lens is provided having a first layer, a second layer and a third layer. The first, second and third layers each comprises a first surface and a second surface. The first layer comprises a substantially non-reactive material. The first surface of the second layer is positioned adjacent to the second surface of the first layer. The second layer comprises a substantially fire resistant material. The first surface of the third layer is positioned adjacent to the second surface of the second layer. The third layer comprises a substantially hydrophobic material.
(FR) Une lentille de protection est pourvue d'une première couche, d'une deuxième couche et d'une troisième couche. Les première, deuxième et troisième couches comprennent chacune une première surface et une seconde surface. La première couche comprend un matériau sensiblement non réactif. La première surface de la deuxième couche est positionnée adjacente à la seconde surface de la première couche. La deuxième couche comprend un matériau sensiblement résistant au feu. La première surface de la troisième couche est positionnée adjacente à la seconde surface de la deuxième couche. La troisième couche comprend un matériau sensiblement hydrophobe.
