Abstract

Abstract Translated from German Auf der Oberseite (7) und der Unterseite (8) eines optisch durchlässigen Plättchens (6) sind halbkugelförmige Linsen (4/1-4/z, 2) aufgebracht. Zwischen den Linsen und dem Plättchen sind Reflexionsfilter (6/1-6/z) vorhanden, die wellenlängenabhängig den einen Teil des auf sie auftreffenden Lichts reflektieren und den anderen Teil durchlassen. Hemispherical lenses (4 / 1-4 / z, 2) are applied to the top (7) and the bottom (8) of an optically transparent plate (6). Between the lenses and the plate there are reflection filters (6 / 1-6 / z) which, depending on the wavelength, reflect one part of the light incident on them and let the other part pass.
