IR Fibre Optic Cables

Infrared wavelengths cannot be transmitted via conventional fibres with a quartz glass core because the coupled light is absorbed by the material. In industry and medicine, CO₂ and Er:YAG (10.6 µm and 2.94 µm, respectively) lasers, therefore, use special fibres for power transmission.

Patchcords for CO₂ Lasers

CO₂ lasers are used in laser material processing and medical applications for the cutting and ablation of tissue because they do not cause bleeding.

Patchcords

The heart of the patchcords is a hollow-core fibre with a core diametre of 500 μm, 750 μm, or 1000 μm. The fibre is generally protected by a metal jacket. The fibre itself is biocompatible and may be sterilized.

So-called SMA905 connectors are used as the main connectors. They are very widely used in laser applications. We also offer options with FC or ST connectors.

Our CO₂ fibres are able to transmit pilot beams and visualize the point of incidence for invisible IR radiation.
