Fiber Bundles
Fused silica glass and optical glass
LEONI produces customer-specific fiber bundles made from
UV-conductive silica/silica (high-OH), IR-conductive silica/silica
(low-OH), plastic or optical glasses with different refractive indices
as appropriate to the requirement for the optically conductive
material on its own drawing systems. The individual fibers are
generally between 30 μm and 150 μm in diameter, but can be drawn
to customer-specific diameters on request. The lengths of the fiber
bundles vary between 4, 5, 10 and 20 m. The bundle diameters
are individually produced according to the customer's wishes.
The fiber bundles are available specifically for endoscopic applications in different radiation angles of 67° (LB type), 83° (LA type),
90° (LW2 type) and ≥100° (L120.3 type) for optimum illumination.
Our range also includes UV-resistant (solarisation-stable) silica/silica
fibers. In addition to endoscopy, they are also used in spectrometry,
lighting and sensor technology.
The individual fibers are coated with glass finish (autoclavable up
to 150°C) or polyimide (can be used up to 300°C) as appropriate
to the assembly and temperature requirements. The thickness
of the coatings is ≤1 µm. They have a protective function and also
simplify the further processing. In addition to the standard lengths
and diameters, the fiber bundles can also be supplied as preassembled optical waveguides with polished end faces.

Assembly of fiber optic bundles
LEONI assembles optical fibers from the suitable base materials
(optical glass or silica) to guarantee the optimum transmission
of the UV light through the visible range to the IR range.
Info
Assembly examples
can be found in the chapter
“Optical Special Components”.
Advantages
■■ The fibers and cables used come from our own production
facilities, which means you can be confident of always getting
the most economical product.
■■ Ultra modern lapping, polishing and cleaving techniques
guarantee maximum transmission properties.
■■ These transmission properties can be further optimised in some
applications through the use of anti-reflective surfaces.
■■ Product diameters and lengths are individually adapted
during assembly.
■■ A selection of protective tube types are presented
in the chapter on tubes.
■■ The assembled fiber bundles can cover a temperature range
from –60°C to +300°C as appropriate to the application.
■■ Customer-specific connector selection:
SMA, SZ, ST connectors or tailor-made ferrules.
