Abstract

Die vorliegende Erfindung betrifft ein Faseraustrittselement (1, 2) mit einer Mehrzahl von Glasfasern (1) mit jeweils wenigstens einem Kern (11), welcher jeweils ausgebildet ist, eine Signallichtstrahlung (A) zu führen, und mit wenigstens einem optischen Element (2), vorzugsweise einem optischen Fenster (2), einer optischen Linse (2), einem optischen Strahlteiler (2), einem optischen Prisma (2) oder einem optisches Linsenarray (2), welches mit jeweils einem offenen Ende der Kerne (11) der Glasfasern (1) verbunden und ausgebildet ist, die Signallichtstrahlung (A) von den offenen Enden der Kerne (11) der Glasfasern (1) zu erhalten und als Austrittsstrahlungen über wenigstens eine Austrittsfläche (26) nach außerhalb abzugeben, wobei die offenen Enden der Kerne (10) der Glasfasern (1), vorzugsweise ferner die offenen Enden von die Kerne (10) im Wesentlichen umschließenden Mänteln (11) der Glasfasern (1), mit jeweils einer Eindringtiefe (W), vorzugsweise gegenüber einer Eintrittsfläche (21) des optischen Elements (2), innerhalb des Materials des optischen Elements (2) angeordnet sind, und wobei wenigstens das Material der offenen Enden der Kerne (10) der Glasfasern (1), vorzugsweise ferner das Material der offenen Enden der Mäntel (11) der Glasfasern (1), mit dem Material des optischen Elements (2) verschmolzen ist. Das Faseraustrittselement (1, 2) ist dadurch gekennzeichnet, dass die Eintrittsfläche (21) des optischen Elements (2) wenigstens eine erste Vertiefung (22a) aufweist und wenigstens eine erste verschmolzene Glasfaser (1a) und eine zweite verschmolzene Glasfaser (1b) durch die erste Vertiefung (22a) der Eintrittsfläche (21) zueinander beabstandet sind.
