Alignment device, system, and method for aligning a beam propagation direction

Abstract

An alignment device (10) for aligning a beam propagation direction (420) of a beam generating unit (400) to an aligning axis (12) of the alignment device (10), wherein the beam generating unit (400) is mountable to the alignment device (10), the alignment device (10) comprising at least four differently shaped cylindric housings (201 . . . n) inserted into each other. Therein, each cylindric housing (201 . . . n) comprises an outer surface (221 . . . n) around its respective cylinder axis (211 . . . n) and an inner cavity (231 . . . n) around a respective cavity axis (241 . . . n) extending through the respective cylindric housing (201 . . . n); the inner cavity (231 . . . n) of each except a smallest of the cylindric housings (201 . . . n) is cylindric; the outer surface (221 . . . n) of each except a largest of the cylindric housings (201 . . . n) is cylindric and at least partially and rotatably arranged in the inner cavity (231 . . . n) of an adjacent one of the cylindric housings (201 . . . n); the inner cavity (23n) of the smallest of the cylindric housings (20n) is configured to at least partially receive the beam generating unit (400); the cavity axis (241 . . . n) of each cylindric housing(201 . . . n) is arranged at an alignment angle (251 . . . n)>0° and/or eccentric to the cylinder axis (211 . . . n) of the respective cylindric housing (201 . . . n); and the aligning axis (12) of the alignment device (10) corresponds to the cylindric axis of the largest of the cylindric housings (201).
