An optical assembly (31) comprising: – a collimating lens (14) which collimates a divergent laser beam (12), – a conical mirror (15) which has a reflecting cover surface (23) and deforms a laser beam, which propagates in the direction of the conical axis (26), into an annular beam (24) in a propagation plane (25) perpendicular to the conical axis (26), – an optics carrier (32) having a first carrier element (33) on which the collimating lens (14) is fixed, and a second carrier element (34) on which the conical mirror (15) is fixed, and – a connection device (35) having at least one connection element (36, 37, 38, 39) which connects the first and second carrier elements (33, 34) to one another, wherein the at least one connection element (36-39) is arranged askew to the conical axis (26) of the conical mirror (15). |
