Abstract

LA INVENCION SE REFIERE A UN DIAFRAGMA DE DIRECCION, QUE SE CARACTERIZA POR UNA MULTIPLICIDAD DE LAMINILLAS (L, FIG.2), QUE FORMAN POZOS DE RADIACION DISPUESTOS DE FORMA PARALELA UNO CON RESPECTO A OTRO. LOS ESPACIOS INTERMEDIOS SON RELLENADOS POR MEDIO DEL CUERPO SOPORTE (T, FIG.1) TRANSPARENTE (FIG.4), CUYO COEFICIENTE DE REFRACCION SE DETERMINA DE TAL MODO, QUE LA LUZ INCIDENTE DE FORMA VERTICAL SOBRE EL PLANO DE INCIDENCIA SE INTERRUMPE. LA INVENCION SE REFIERE TAMBIEN A UN PROCEDIMIENTO PARA SU ELABORACION.
