Abstract[English]
The present invention relates to an instrument (1) for objectively measuring the dispersion of light, which is useful in the cinematography and audiovisual sector. The invention overcomes the lack of precise tools, eliminating the relativity of the concept. The instrument of the invention consists of a semi-sphere (2) made of a matte material and having a known size, serving as a constant subject. When the instrument is oriented toward a light source, an external device captures an image of the dispersion of light over the semi-sphere (2), providing an objective measurement of the dispersion. The instrument can include marks (3) for orientation, a mirrored semi-ellipsoid (5) for complementary analysis of the source, and sight holes (6, 7) for alignment. The primary use of the instrument is for evaluating and standardising the measurement of the dispersion of light on a known and constant object that takes the place of a subject.[Spanish]

Consta de una semi-esfera (2) de material mate y tamaño conocido como sujeto constante. Al orientarlo a una fuente lumínica, un dispositivo externo captura la imagen de la dispersión de luz sobre la semi-esfera (2), proporcionando una medida objetiva de la dispersión. Puede incluir marcas (3) para orientación, un semi-elipsoide espejado (5) para análisis complementario de la fuente, y mirillas (6, 7) para alineación. Su uso principal es evaluar y estandarizar la medida de la dispersión sobre un objeto conocido y constante que sustituye a un sujeto.[French]

Il peut comprendre des repères (3) pour l'orientation, un demi-ellipsoïde à miroirs (5) pour l'analyse complémentaire de la source, et des fentes de visée (6, 7) pour l'alignement. Son utilisation principale est l'évaluation et la standardisation de la mesure de la dispersion sur un objet connu et constant qui remplace un sujet.
