Abstract

Die Erfindung betrifft eine Lichtleitfaser und Preform zur Herstellung der Lichtleitfaser, bestehend aus einem Kernbereich und einem Mantelbereich mit einer bezüglich einer bezüglich eines Brechzahlniveaus einer Glasmatrix erhöhten Kernbrechzahl und einer bezüglich des Brechzahlniveaus der Glasmatrix erniedrigten Mantelbrechzahl, wobei die numerische Apertur der Lichtleitfaser von dem Kernbereich und dem Mantelbereich bestimmt ist. Dabei ist zwischen dem Kernbereich und dem Mantelbereich eine Distanzschicht mit einer Dicke ausgebildet ist, bei welcher die numerische Apertur der Lichtleitfaser oder der Preform durch die Brechzahlen des Kernbereichs und des Mantelbereiches bestimmt ist.
