透镜
扫描镜头按照设计理念分f-theta透镜和远心透镜。属于小孔径小视场光学系统，要求扫描光斑小，接近衍射极限，可以实现激光光斑的扫描聚焦。扫描镜头的主要技术参数有：工作波长、入射光瞳、扫描范围 和聚焦光斑直径。
1. 像面场曲小(Flat Field at the Image Plane)
2. 聚焦光斑小
3. 成像质量达到衍射极限(Diffraction Limited Performance)
4. 镜片镀膜高损伤阈值(Air Spaced Designs for High Damage Threshold)
5. 扫描波长覆盖紫外、白光、红外(Designs from the Ultraviolet to the Visible and Infrared Regions)
