LWDM filter
應用于LWDM Z-BLOCK的紅(hóng)帶或藍帶LWDM細波分(fēn)複用濾波片,光(guāng)譜指标優異、面型尺寸精準和熱(rè)可(kě)靠性高,入射角AOI 8度或13.5 度或定制

AOI 8/13.5 epoxy type LWDM TFF filter 是專門(mén)爲LWDM Z-BLOCK mux光(guāng)學組件(jiàn)應用而設計(jì)的LWDM濾波片,它采用8/13.5度大(dà)入射角設計(jì)來(lái)壓縮BLOCK尺寸,采用粘接面爲波長工(gōng)作(zuò)膜面設計(jì)來(lái)消除濾波片雙面加工(gōng)公差帶給光(guāng)斑光(guāng)束的偏移誤差。它具有面型品質高,便于粘接,光(guāng)束平行度高;膜層損傷阈值高,匹配高功率遠(yuǎn)距離(lí)EML激光(guāng)器;通道中心波長一緻性好,帶寬大(dà),PIV曲線(LD輸入電流值與BLOCK後端的光(guāng)功率測量值)的線性工(gōng)作(zuò)區間大(dà),TOSA ROSA機(jī)器耦光(guāng)效率高;采用微晶基材,熱(rè)穩定性高。接受客戶不同種規格指标的開爐定制。
