尾纖型準直器
單模光纖尾纖型準直器
APS系列單模光纖尾纖型準直器由一個不銹鋼(或鈦合金)外殼和一個非球面透鏡組成。每個準直器帶一米長的單模尾纖,在設計波長處具有衍射極限性能。與非球面透鏡準直一側的光纖端面成8°傾角拋光,非球面透鏡雙側鍍有增透膜,可以最大程度地減小設計波長處的反射率(回波損耗>60 dB)。采用內部角度補償結構,避免為了匹配光纖端面傾角而使用彎折外殼(針對外徑為9 mm的準直器)。對于焦距小于5 mm的型號,光纖端面傾角引起的偏差可以忽略,因而這些版本的外殼也是直的。

保偏光纖尾纖型準直器
APP系列保偏光纖尾纖型準直器由一個不銹鋼(或鈦合金)外殼和一個非球面透鏡組成。每個準直器帶一米長的單模尾纖,在設計波長處具有衍射極限性能。與非球面透鏡準直一側的光纖端面成8°傾角拋光,非球面透鏡雙側鍍有增透膜,可以最大程度地減小設計波長處的反射率(回波損耗>60 dB)。由于焦距小于5 mm,光纖端面傾角引起的偏差可以忽略,因而這些版本的外殼均為直的。如右圖所示,外殼上的刻線平行于慢軸,耦合偏振光時可以用作參考。
