尾纤型准直器
单模光纤尾纤型准直器
APS系列单模光纤尾纤型准直器由一个不锈钢(或钛合金)外壳和一个非球面透镜组成。每个准直器带一米长的单模尾纤,在设计波优点具有衍射极限性能。与非球面透镜准直一侧的光纤端面成8°倾角抛光,非球面透镜双侧镀有增透膜,可以最洪流平地减小设计波优点的反射率(回波损耗>60 dB)。接纳内部角度赔偿结构,制止为了匹配光纤端面倾角而使用弯折外壳(针对外径为9 mm的准直器)。关于焦距小于5 mm的型号,光纤端面倾角引起的偏差可以忽略,因而这些版本的外壳也是直的。
保偏光纤尾纤型准直器
APP系列保偏光纤尾纤型准直器由一个不锈钢(或钛合金)外壳和一个非球面透镜组成。每个准直器带一米长的单模尾纤,在设计波优点具有衍射极限性能。与非球面透镜准直一侧的光纤端面成8°倾角抛光,非球面透镜双侧镀有增透膜,可以最洪流平地减小设计波优点的反射率(回波损耗>60 dB)。由于焦距小于5 mm,光纤端面倾角引起的偏差可以忽略,因而这些版本的外壳均为直的。如右图所示,外壳上的刻线平行于慢轴,耦合偏振光时可以用作参考。
