Eine optische Anordnung umfasst eine Lichtquelle, die kohärentes Licht emittiert, und ein optisches Gitter (1) mit einer Vielzahl paralleler, periodisch im Abstand jeweils einer Gitterperiode aufeinanderfolgender Beugungsstrukturen (3). Diese bilden zusammen eine Reflexionsschicht, die eine reflektierende Grundschicht oder einen reflektierenden Träger (2) sowie eine mit der Grundschicht oder dem Träger (2) verbundene und diese abdeckende transparente Gesamschutzschicht (7) umfasst. Die Beugungsstrukturen (3) sind auf einem eine Grundfläche (4) vorgebenden Träger (2) angeordnet und weisen jeweils eine im wesentlichen im Littrow-Winkel zur Grundfläche (4) geneigte Blaze-Flanke (5) und eine Gegenflanke (6) auf. Die Schichtstärken der Schutzschichten (8, 9) auf der Blaze-Flanke (5) und auf der Gegenflanke (6) die gemeinsam die Gesamtschutzschicht (7) bilden, sind unabhängig voneinander derart gewählt, dass die Gitterperformance, also entweder die Absorption oder die Beugungseffizienz des optischen Gitters (1) optimiert ist. Je nach Anwendungsfall resultiert ein optisches Gitter (1) mit geringeren Anforderungen an die Lichtquelle oder ein optisches Gitter, welches durch das einfallende Licht möglichst wenig beeinflusst wird. Zudem wird ein Herstellungsverfahren für ein optisches Gitter einer derartigen optischen Anordnung angegeben.

The light beam (12) is directed onto the at least one optically operative surface (22) with a ring-segment-shaped cross section (26) transversely with respect to the light propagation direction. A device (10), in particular for carrying out the method, and an optical arrangement (70a) for generating a light beam with a ring-segment-shaped cross section are likewise described.
