    Chalcogenide (CIR) Fiber Bundles, Convertors and Splitters

    art photonics GmbH development of specialty fibers for the Mid-IR region has resulted in a unique product – Chalcogenide Infra-Red (CIR-) fibers. Chalcogenide glasses (As₂ S₃) transmit IR-radiation in the spectral range of 1.1 – 6μm. Our CIR fibers are drawn in core/clad structure with double polymer coating and characterized by low total optical losses and low absorption peaks over mentioned spectral range.

    High flexibility & high transmission of our chalcogenide fibers allowed producing commercial fiber bundles & convertors for Mid-IR applications.
