| 摘要 |
The invention relates to an optical element (1) that is to be mounted on a shaft (2), particularly a spindle shaft, in order to deflect a laser beam (3). Said laser beam (3) is deflected via a first (4) and a second mirror surface (5). At least one additional surface (6, 7) is provided for reducing centrifugal forces and gyroscopic moments acting upon the shaft (2). |
