Abstract

Lente asférica axisimétrica para generación de una respuesta angular específica. Consiste en una lente asférica axisimétrica (3) que proporciona una sensibilidad angular específica a un dispositivo receptor o una intensidad angular específica a un dispositivo emisor (2). La respuesta angular a proporcionar al dispositivo emisor o receptor se especifica como dato de partida del procedimiento de diseño. La novedad de esta invención reside en la capacidad de la lente objeto de la invención para proporcionar respuestas angulares específicas en geometría tridimensional axisimétrica con gran precisión sin imponer ninguna restricción al tamaño relativo entre la lente y los dispositivos emisores o receptores. Son posibles campos de aplicación de dicha lente: los sistemas de detección de radiación y de telealimentación, específicamente los electrónicos basados en fotodiodos o células fotovoltaicas; los sistemas de iluminación con diodos LED, o las comunicaciones ópticas sin hilos con un IRED o con un láser como emisor y con un fotodiodo o fototransistor como receptor.Asymmetric axisymmetric lens for generating a specific angular response. It consists of an axisymmetric aspherical lens (3) that provides a specific angular sensitivity to a receiving device or a specific angular intensity to a sending device (2). The angular response to be provided to the sending or receiving device is specified as the starting data of the design procedure. The novelty of this invention lies in the ability of the lens object of the invention to provide specific angular responses in axisimetric three-dimensional geometry with great precision without imposing any restrictions on the relative size between the lens and the emitting or receiving devices. Fields of application of said lens are possible: radiation detection and tele-feeding systems, specifically electronic ones based on photodiodes or photovoltaic cells; lighting systems with LEDs, or wireless optical communications with an IRED or with a laser as a transmitter and with a photodiode or phototransistor as a receiver.
