消色差双胶合透镜
西格玛光机双胶合消色差透镜DLB由折射率和色散不同的2个透镜组成的胶合透镜，与球面单透镜相比，可以校正色差和球差。西格玛消色差双胶合透镜DLB可以作为望远镜的物镜或激光实验的准直透镜使用。通过优化透镜设计，在整个可见光谱区焦距几乎不变。除色差外，球差也得到了良好地校正，因此Optosigma消色差双胶合透镜DLB作为激光的准直透镜十分合适。除轴上物点的色差外，轴外的慧差或像散也得到了良好地校正。DLB消色差双胶合透镜可以用于望远镜的物镜或显微镜的成像透镜等的成像系统。您可以从从丰富细化的外径尺寸和焦距的系列产品中，选择符合您的技术要求的产品。

西格玛消色差双胶合透镜DLB产品信息
- 西格玛光机可承接制造产品目录之外的焦距或外径的产品。
- Sigmakoki承接设计制造客户要求的波长区域的消色差透镜。
- 透镜的具体设计数据，请在官网上确认。
- Optosigma备有激光加工用的空气隙型聚光透镜（NYTL/NYDL）。
消色差双胶合透镜DLB使用注意事项
- 西格玛消色差双胶合透镜DLB令无限远物体成像于焦点位置，或将点光源转化为平行光。如果要对近距离的物体进行成像，透镜的光学性能将不能得到充分发挥。
- 入射消色差透镜的平行光有方向性，要从曲率半径较小的一侧（有箭头符号指向的一面）射入平行光。从相反的一侧射入平行光时，会产生色差或球差，焦点光斑会变大。
- 在可见光以外的波长条件下使用，色差可能会变大，而且，透过率可能降低。

200/308/400消色差透镜
紫外消色差聚焦透镜是NA为0.1以下的透镜，对准直激光成像后的焦点光斑直径几乎接近衍射极限。没有使用吸收紫外光的玻璃或粘接剂，具有良好的耐光性。

可见光气隙消色差聚焦双合透镜
可见光气隙消色差聚焦透镜不使用胶合透镜，而使用空气隙型消色差的聚光透镜。可以嵌入激光加工机械中，使用机内的532nm高输出激光进行同轴照明，作为聚光透镜使用。通过光学优化设计，校正了以532nm为中心的宽带范围内色差。

ETL/EDL/NEDL准分子激光空气隙透镜
准分子激光空气隙透镜是在紫外光谱区域有高透过率的合成石英透镜构成的紫外激光用聚光透镜。没有使用吸收紫外光的玻璃或粘着剂，所以耐光性很好。248nm透镜由2枚或3枚球面透镜的组成，校正了球差和慧差。

西格玛光机非球面平凸透镜
把平凸透镜的凸面改成非球面形状，可制作球差小的短焦距透镜，也就是OptoSigma非球面平凸透镜。西格玛光机非球面平凸透镜常被用于汇聚照明光，或准直点光源。
