Abstract
Nueva combinación prismática para la observación periscópica que permite aumentar el valor del campo angular en emplazamiento, reduciendo simultáneamente el espesor y el peso de las masas prismáticas truncadas que la constituyen y caracterizada por el hecho de que las mencionadas masas prismáticas, en lugar de comprender dos superficies de extremos paralelos inclinados en 45º con relación a las superficies de entrada y de salida de los rayos luminosos y hacer solo que estos rayos experimenten dos reflexiones, comprenden dos superficies paralelas inclinadas en un ángulo notablemente inferior a 45º que determinan un camino óptico en línea quebrada experimentado el haz luminoso cuatro reflexiones, de las cuales dos se realizan sobre las mencionadas superficies de extremo inclinadas y dos suplementarias sobre las mencionadas superficies de entrada y salida.
