IRF-Se Series Chalcogenide Nonlinear Longwave Mid-Infrared Fiber

IRflex Corporation is now extending its family of fiber products into longwave mid-infrared spectral region.  IRflex’s IRF-Se Series chalcogenide nonlinear longwave mid-infrared fibers, made from extra high purity chalcogenide glass As2Se3, are specially designed and manufactured to generate and/or guide mid-infrared wavelengths from 1.5 to 10 µm with high transmission efficiency and nonlinearities about 1000 times that of silica glass fiber.

IRF-Se series have IRF-Se-12 singlemode, plus IRF-Se-100 R&D, IRF-Se-150 and IRF-Se-300 multimode fiber models available for commercial sales.  They have broad transmission range from 1.5 to 10 µm.  The typical optical loss is less than 0.168dB@ 3.89 µm, aided by extremely high purity content, with core non-circularity of less than 1%, and core/clad concentricity error of less than 3 µm. 

IRF-Se series fiber can be offered connectorized or as bare fiber.
