线性偏振激光束的电动可变衰减器990-0070M
具有ø17 mm通光孔径的电动可变衰减器，由两个薄膜Brewster型偏振片和λ/ 2波片安装在精密的电动旋转安装座中。衰减器是为许多流行的激光波长设计的。
产品介绍
该电动可变衰减器/分束器包括特殊设计的光机械适配器和精密光机械支架840-0193。适配器中装有两个薄膜Brewster型偏振片，它们反射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。
