Abstract

La presente invención se refiere a mejoras en un aparato de interconexión óptica para transmitir una señal de luz a un aparato que funciona con luz que comprende un lente espaciador que recibe la señal, caracterizadas en que un segmento de colimador con una superficie en forma de un paraboloide de revolución está conectado con el lente espaciador y actúa de modo que, la señal de luz que entra al segmento colimador como haz divergente de luz se afoca con una superficie parabólica relacionada con el paraboloide de revolución como haz paralelo de luz; el lente espaciador y el segmento de colimador, cuando están conectados, forman un colimador y lente de configuración monolítica y conectado con el aparato que funciona con luz, para dirigir al mismo el haz paralelo de luz.
