Abstract
An optical assembly is disclosed. The optical assembly includes a collimating lens which collimates a divergent laser beam. A conical mirror has a reflecting cover surface and deforms a laser beam, which propogates in the direction of the conical axis, into an annular beam in a propogation plane perpendicular to the conical axis. An optics carrier has a first carrier element on which the collimating lens is fixed and a second carrier element on which the conical mirror is fixed. A connection device has at least one connection element which connects the first and second carrier elements to one another. The at least one connection element is arranged askew to the conical axis of the conical mirror.

An optical assembly, comprising:
- a collimation lens, wherein the collimation lens collimates a laser beam to form a collimated laser beam;
- a conical mirror with a reflecting exterior surface, wherein the conical mirror converts the collimated laser beam, which propagates in a direction of a conical axis of the conical mirror, into an annular beam and deflects the annular beam to propagate in a propagation plane that is perpendicular to the conical axis;
- an optics carrier with a first carrier element, wherein the collimation lens is fixed to the first carrier element, and with a second carrier element, wherein the conical mirror is fixed to the second carrier element;
- and
- a connection device with at least one connection element, wherein the at least one connection element connects the first carrier element and the second carrier element to each other;
- wherein the at least one connection element is disposed askew to the conical axis of the conical mirror.
