Description
Chalcogenide As-S glass fiber is capable of transmitting IR radiation within the spectral range of 1.1 - 6.5μm. High-performance CIR (Core/Clad Infrared) fibers are manufactured through a drawing process, featuring core diameters ranging from 8µm to 500µm. These fibers exhibit exceptional mechanical strength and flexibility due to an advanced drawing technique and a double polymer jacket.
The CIR fibers are designed to minimize optical losses and exhibit minimal absorption peaks throughout the aforementioned spectral range. This characteristic enables the successful utilization of CIR-fiber across a wide range of applications.
