Our 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 Mid-IR fibers allowed producing commercial fiber bundles & convertors for mid-IR applications for spectral range from 1.5µm up to 18µm.

| Optical connectors | SMA; long SMA; FC/PC; ST | |
Round-to-round (R/R) and round-to-line (R/L) fiber bundles are probably the most popular and demanded, since they are used in the manufacture of a wide range of fiber optic sensors and probes. We offer optical fiber bundles in straight, bifurcated multi-furcated design. For spectroscopy fiber probes we are offering unique bundles with metal-coated fibers, which allow to block the cross-talk between the fibers, and in result signal/noise ratio is higher than in similar bundles with fiber polymer coatings. Our silica fiber bundles are terminated with SMA905, FC/PC, ST or custom connectors and for spectral range from 0.2µm up to 2.2µm.
