Patent ID: 7345800

Claim:
An optical arrangement for deflecting a light beam, comprising: a first deflection device rotatable about a first axis using a first rotary drive, the first deflection device including a first and a second minor disposed non-rotatably with respect to each other in an angular position so as to rotate jointly about the first axis; a second deflection device rotatable about a second axis using a second rotary drive, the second deflection device including a third minor; and a coupling mirror configured to deflect the light beam onto one of the first and second mirrors at an angle greater than 45° relative to the surface of the one mirror; wherein the first and second axes are perpendicular to each other; wherein the first and a second minors are configured to rotate jointly about the first axis so that the tight beam rotates about a center of rotation located on the second axis; and wherein the coupling mirror is disposed between the second rotary drive and a mirror of the first and second mirrors that is closest to the first rotary drive.
