保偏隔離器是采用保偏光纖制作的光隔離器。光隔離器是一種只允許單向光通過(guò)的無(wú)源光器件,其工作原理是基于法拉第旋轉(zhuǎn)的非互易性。對(duì)于正向入射的信號(hào)光,通過(guò)起偏器后成為線偏振光,法拉弟旋磁介質(zhì)與外磁場(chǎng)一起使信號(hào)光的偏振方向右旋45度,并恰好使其低損耗通過(guò)與起偏器成45度放置的檢偏器;對(duì)于反向光,出檢偏器的線偏振光經(jīng)過(guò)放置介質(zhì)時(shí),偏轉(zhuǎn)方向也右旋轉(zhuǎn)45度,因此反向光的偏振方向與起偏器方向正交,完全阻斷了反射光的傳輸。光隔離器常用于光纖通信系統(tǒng)和精密光學(xué)測(cè)量系統(tǒng)中。飛凡光電(深圳)有限公司精心為您提供多種在線式保偏光隔離器主要包括1030nm、1064nm,1310nm ,1550nm波段的,具有低插入損耗,高隔離度,高回波損耗以及高消光比等特性。您可以根據(jù)自己的具體用途,選擇合適的保偏隔離器。如果您需幫助,或者您有其它的器件需求,可以在線聯(lián)系我們的銷售并告知您的需要,我們會(huì)第一時(shí)間回復(fù)您。
