概述光学元件

C型偏振片

利用这些光学元件,可制造环形器、数据终端设备(DTE)、数据通信设备(DCE)、交织器及其他电信 。

Coherent C-polarizers combine a birefringent YVO4 beam displacer and a λ/2 waveplate to provide a compact, monolithic way of separating or combining polarization-multiplexed optical signals with high polarization purity in an epoxy-free optical path.
