具有ø10 mm透明光圈的电动可变衰减器，可以连续改变出射的s-pol和p-pol光束的强度比。 衰减器由薄膜偏振片，高性能波片和精密光机械组成。

产品介绍

这款电动可变衰减器/分束器包括特殊设计的，用于56°840-0117A或840-0118A偏振片的光机械适配器和精密光机械支架840-0193。薄膜布鲁斯特型偏振片被容纳在56°的偏光镜适配器中，该偏振片在56°时反射S偏振光，同时透射P偏振光。石英半波片安装在电动旋转平台960-0161中。可以通过旋转波片连续改变这两个光束的强度比，而不会改变其他光束参数。

可以在很宽的动态范围内控制出射光束的强度或其强度比。可以选择P偏振以获得较大的透射率，或者当透射光束发生较大衰减时可以反射高纯度s偏振。保持器840-0193允许将薄膜布鲁斯特型偏振片的入射角调整±2°，并获得较大的偏振对比度。


注意：控制器和电源应单独订购。
