Summary:The invention relates to an optical arrangement for a laser beam (5), in particular a scanner device (1), comprising an F-Theta lens (3). The F-Theta lens (3) is arranged in a diverging beam path (4) of the optical arrangement (1) for focusing a laser beam (5) into a focal plane (FE) which is located at a distance from a focal plane (FB) of the F-Theta lens (3). 本发明涉及一种用于激光束(5)的光学布置，尤其是扫描仪设备(1)，包括：F-Theta镜头(3)。该F-Theta镜头(3)布置在光学布置(1)的发散的射束路径(4)中，用于将激光束(5)聚焦到聚焦面(FE)中，该聚焦面位于距该F-Theta镜头(3)的焦平面(FB)一定间距处。
