Abstract
(DE)
Es wird ein optischer Körper (1) angegeben mit - einem Matrixmaterial (2) mit einem Brechungsindex kleiner gleich 1,5; - einer Vielzahl an Streupartikeln (3) mit einem Brechungsindex von größer gleich 2,0; und - einer Vielzahl von Poren (4), die mit einem Gas gefüllt sind. Darüber hinaus werden ein Reflexionselement (5) und ein Bauelement (7) mit einem solchen Reflexionselement (5) angegeben. Zusätzlich wird ein Verfahren zur Herstellung eines optischen Körpers (1) und zur Herstellung eines Reflexionselements (5) angegeben.
(EN)
The invention relates to an optical body (1) having - a matrix material (2) having a refractive index which is less than or equal to 1.5; - a plurality of scattering particles (3) having a refractive index of greater than or equal to 2.0; and - a plurality of pores (4), which are filled with a gas. Furthermore, the invention relates to a reflection element (5) and to a component (7) having such a reflection element (5). The invention additionally relates to a method for producing an optical body (1) and for producing a reflection element (5).
(FR)
L'invention concerne un corps optique (1) comprenant : un matériau de matrice (2) ayant un indice de réfraction qui est inférieur ou égal à 1,5 ; une pluralité de particules de diffusion (3) ayant un indice de réfraction supérieur ou égal à 2,0 ; et une pluralité de pores (4), qui sont remplis d'un gaz. En outre, l'invention concerne un élément réfléchissant (5) et un composant (7) comprenant un tel élément réfléchissant (5). L'invention concerne en outre un procédé de production d'un corps optique (1) et un procédé de production d'un élément réfléchissant (5).
