| 摘 要： | 介绍一种适合于激光打标的聚焦镜头－F-θ镜头的光学设计.通过引入桶形畸变，得到的F-θ镜头的像高与入射角成正比，可实现打标速度的线性控制.优化设计得到的工作面积达500×500 mm2的F-θ镜头，结构简单紧凑、聚焦性能达到衍射极限.

| Abstract: | The optical design of F-θ lens,which is fit for laser marking as the focusing lens was introduced.Introducing barrel distortion,the image height of F-θ lens is in proportion to its incident angle,and it made marking linearly.F-θ lens with its working area 500×500 mm2 was obtained after optimal design.It was compact and its performance was within diffraction limit. |
