LIEKKI® Coreless Passive Fibers

LIEKKI® coreless passive fibers are designed and manufactured to be used as end caps in fiber amplifiers and lasers. The fibers contain no core and consist only of a silica cladding which is coated by a dual layer low index acrylate. LIEKKI® coreless passive fibers are ideal for reducing back reflections from fiber ends and preventing fiber damage at the end face in high power applications.
