Heraeus - Highly Fluorine Doped Tubes Datasheet

Fluosil" tubes ate characterized by the unique high fluorine concentration, which leads to a depressed index of refraction up to -26 xlO`³. Our Fluosil* tubes feature the highest fluorine content and therefore the lowest refractive index in the market. They can be manufactured as homogenous single layer as well as multiple layer composite tubes with a polygonal structure e.g. as pump cladding for fiber laser core rods.
