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 (As2S3) 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.
Features:
- High transmittance from 1.5µm to 6µm
- Optical losses 0.2 dB/m at 2 – 4 µm
- Double polymer coating for high flexibility
- Standard fiber diameters from 8 to 500µm
Applications:
- Flexible IR-imaging systems
- Remote non-contact pyrometry in the 200-600K range
- Fiber probes for remote process IR – spectroscopy
- Fiber amplifiers and lasers
