Abstract
Lente asférica anaxisimétrica para acoplamiento de cuatro congruencias normales de rayos, dos a dos. Está compuesta por dos dióptricos esféricos sin simetría de revolución que transforman dos congruencias normales de rayos en otras dos, estando los cuatro haces especificados de partida. Su originalidad estriba en que no existe ninguna invención previa que realice la función que dicha lente desempeña. Un caso particular de especial interés se obtiene cuando la lente transforma dos congruencias asociadas a dos frentes de onda planos en otras dos asociadas a frentes de onda esféricos (ver gráfico). Son posibles aplicaciones de dicha lente, en combinación con un conjunto de microlentes cilíndricas: las comunicaciones infrarrojas sin hilos a media distancia basadas en el estándar IrDA, los sistemas de iluminación con diodos emisores de luz (LED) con mezclado de colores y sistemas de detección de distancia o de presencia, con emisor IRED y detector fotodiodo o PSD.Anaxisimetric aspherical lens for coupling four normal ray congruences, two by two. It is made up of two spherical diopters without symmetry of revolution that transform two normal ray congruences into two others, the four specified beams being the starting point. Its originality lies in the fact that there is no previous invention that performs the function that said lens performs. A particular case of special interest is obtained when the lens transforms two congruences associated with two plane wave fronts into two other congruences associated with spherical wave fronts (see graph). Applications of this lens are possible, in combination with a set of cylindrical microlenses: the wireless infrared communications at medium distance based on the IrDA standard, the illumination systems with light-emitting diodes (LEDs) with color mixing and detection systems distance or presence, with IRED emitter and photodiode or PSD detector.
