Title (EN) METHODS FOR FABRICATING GRADED, LARGE SIZE, SELF-REFRIGERATING LENSES WITH VARIABLE FOCUS AND FILTER PROPERTIES
(ES) PROCEDIMIENTOS PARA LA FABRICACION DE LENTES ESCALONADAS DE GRAN TAMAÑO, AUTOREFRIGERABLES, CON FOCO Y PROPIEDADES FILTRANTES VARIABLES
(FR) PROCEDES DE FABRICATION DE LENTILLES ECHELONNEES DE GRANDE DIMENSION, AUTOREFRIGERABLES, AVEC FOYER ET PROPRIETES FILTRANTES VARIABLES
Abstract:
(EN) Methods for the fabrication of large size, self-refrigerating graded lenses with variable focusing and filtering properties, comprising the conformation of fine sheets of transparent and rigid materials through conventional processes (heat molding, extrusion, injection, etc) in order to obtain recipients with graded cavities which communicate between each other and are capable of maintaining conformed fluids (still or circulating) of which the refraction indexes and/or filtering properties are different from those of the external medium in order to refract or filter radiating beams by causing them to converge or diverge.
(ES) Procedimientos para la fabricación de lentes escalondadas de gran tamano, autorefrigerantes, con foco y propiedades filtrantes variables, consistente en el conformado de láminas finas de materiales transparentes y rígidos, mediante procedimientos convencionales (termomoldeo, extrusión, inyección, etc.) para la obtención de recipientes con oquedades escalonadas, comunicadas entre sí, capaces de mantener conformados fluidos (en reposo o circulantes), cuyos índices de refracción y/o propiedades filtrantes, sean distintos a las del medio exterior, con el fin de conseguir refractar o filtrar haces radiantes, haciéndoles converger o divergir.
(FR) L'invention concerne des procédés de fabrication de lentilles échelonnées de grande dimension, autoréfrigérables, avec foyer et propriétés filtrantes variables. Ces procédés consistent à conformer des feuilles fines de matériaux transparents et rigides au moyen de procédés classiques (thermomoulage, extrusion, injection, etc.) afin d'obtenir des récipients pourvus de cavités échelonnées, communicant entre elles, capables de maintenir des fluides conformés (au repos ou circulants) dont les indices de réfraction et/ou propriétés filtrantes sont différents de ceux du milieu extérieur, afin de réaliser une réfraction ou filtration des faisceaux rayonnants en les faisant converger ou diverger.
