LargeCore Fiber
Special fibers – fused silica glass, sapphire, non-oxidic glasses
Fibers made from super pure silica are used for optimum
light transmission from the ultra-violet range (UV) to the
infrared range (IR).
We have drawing systems on which large-diameter UV-conductive
silica/silica fibers (high-OH), IR-conductive silica/silica fibers
(low-OH) or capillaries and tapers are drawn.
The fibers are available individually or in different buffered fiber
and cable constructions. We supply core diameters from 3 μm
to 10 μm for singlemode applications and from 20 μm to 2 mm
for multimode applications such as spectroscopy, medical technology,
energy transmission (laser technology) and sensor technology.
Silica fibers are covered with a coating consisting of acrylate,
dual acrylate, high-temperature dual acrylate, silicone or polyimide.
The fibers are covered with a further buffer, made from Nylon®
or Tefzel® for example, so that they can be used in different
temperature ranges and chemical environments. The apertures
of the silica optical fibers can vary from 0.1 to 0.49.
We offer special fibers (sapphire fibers, various doped fibers, germanium oxide fibers) and special coatings (metal) for customer-specific requirements.
