CA 2289853
The invention relates to a flexible, two-dimensional screening material, especially for protecting human skin or cutaneous tissues against undesirable radiation. Said screening material is configured as an optical filter, and has diffracting and/or reflecting edges running parallel to each other. The reciprocal distance (A) between said diffracting and/or reflecting edges is equal to a multiple of the wavelength of the rays against which the skin is being protected.
L'invention concerne un matériau de recouvrement souple en nappe, en particulier pour la protection de la peau ou de tissus cutanés humains contre des rayons indésirables, le matériau de recouvrement étant réalisé sous forme de filtre optique et présentant des arêtes de diffraction ou de réflexion parallèles dont la distance mutuelle A est un multiple de la longueur d'onde des rayons contre lesquels doit s'effectuer la protection.
