产品说明
- 工作波长：400-700 nm、700-1700 nm
- 包含两片薄膜线性偏振片
- 应用：连续降低亮度
LBTEK可调偏振镜由两片薄膜线性偏振片组成，偏振片各自由前后两层N-BK7玻璃衬底与中间的线性偏振薄膜组成，能够连续降低亮度用作光强衰减器。当两片偏振片的透射轴与入射光偏振方向平行时，透过率达到最大，此时转环对准（＋）标记；当入射偏振片透射轴与入射光偏振方向平行，出射偏振片透射轴与入射偏振片透射轴垂直时，透过率最小，此时转环对准（-）标记。LBTEK提供工作波长为400-700 nm和700-1700 nm的可调偏振镜。

可调偏振镜，薄膜线性偏振片
- 包含两片经济型薄膜线性偏振片
- 低功率应用
- SM1内外螺纹
可调偏振镜入射端与出射端分别采用SM1外螺纹和SM1内螺纹的结构设计，便于连接各类光学元件或组件。将偏振镜旋入SM1内螺纹组件后，可使用PCW-A扳手（单独出售）锁紧SM1LR锁定环，既能稳固固定偏振镜，也可调校入射偏振片透射轴，使其与输入光源偏振方向精准匹配。旋转出射偏振片，可连续调节出射光强度并改变偏振方向，参数调试完毕后，拧紧M3×2.5平头紧定螺钉即可完成锁定。
