双波长产品
在多波长光束中，双波长产品是用于将具有不同波长的两个入射光束组合到同一焦点中的衍射光学元件，。
特别地，该聚焦组合器用于将CO2 激光器和可见瞄准光束聚焦到单个焦点，从而实现了两个光束在相同的光路上的医疗光束组合器。
双波长校正了CO2 激光与其可见瞄准光束之间的强色差。该混合元件为一在其平面侧具有相应衍射图样元件的平凸透镜设计成。根据客户的应用确定需求，两种波长的焦距是在设计期间即可确定。
HOLO / OR为医疗和扫描仪系统提供带双波长透镜的F-Theta衍射透镜。此选择无需将双波长透镜放置在扫描仪内部，并提供了焦距偏移和场校正。这些元件由下表中带FT的零件号表示（如FT-001-AP-YA）。
