Description
This is a Chalcogenide IR-Fiber Cable produced by art photonics GmbH.
art photonics development of specialty fibers for the Mid-Infrared region has resulted in a unique product – Chalcogenide Infra-Red (CIR-) fibers. Based on chalcogenide glasses (As₂ S₃) they transmit IR-radiation in the spectral gap between Silica fibers (0.2-2.4μm) and Polycrystalline InfraRed (PIR) fibers (4-18μm) in the range of 1.5 - 6μm.
Our single- and multimode CIR fibers are drawn in core/clad structure with double polymer coating and characterized by a low optical loss.
The advantage of chalcogenide IR-fibers: Chalcogenide glasses are an amalgam of chalcogen elements: typically selenium (Se), sulfur (S), and tellurium (Te). Arsenic (As), Germanium, and other elements might be added to facilitate the cross linking between the chains of chalcogens and render a resilient glass material. Chalcogenide IR fibers made of such glass offer useful physical characteristics including low optical loss transmission in the mid-IR and far IR wavelength regions, high refractive index, and relatively large nonlinearities compared to their silica alternatives.
