Abstract

Oftalmoscopio binocular indirecto, cuyo sistema de observación está reunido, en una unidad de construcción, con una varilla de lámpara, estando dispuesto el eje óptico de la barra de lámpara, constituida en forma de mango, en ángulo agudo respecto al eje de observación y estando situados ambos ejes en un plano, caracterizado porque debajo de la fuente de luz de la barra de lámpara está dispuesto un ventilador refrigerador, junto con motor impulsor, que hace salir hacia abajo el aire refrigerante, mientras que el sistema de observación se compone de dos espejos inversores con correspondientes oculares, con distancia variable, que están montados sobre una placa, que se extiende en un plano perpendicularmente al eje de observación, asi como de un prisma divisor de rayos, que presenta dos superficies planas, que re reunen en ángulo recto, que para la desviación de la radiación presenta una superficie plana adicional, que forma intersección con el canto de encuentro de ambas superficies planas.
