Multimode special optical fibers
Multimode special optical fibers
Laser beam transmission with applications in manufacturing, medicine, spectroscopy, sensor technology and high-power laser transmission
Graded-index and step-index multimode fibers are used for data and power transmission. Undoped Fused Silica as a core material offers low attenuation and permits higher-power transmissions, e.g. from high-power lasers. Doped silica is used if a high numerical aperture is required for optimal launching of light into the fibers or to implement special fiber profiles. The size and shape (geometry) of the fiber core can be adjusted to match application requirements. With a suitable coating material and an optional buffer layer, the fibers can be protected from a wide range of environmental factors. All fibers can be adjusted, optimized, and assembled specifically for the customer’s individual application scenario along the entire value chain – from the initial manufacture of the Fused Silica starting material through to the final assembly.
We offer a broad portfolio of optical fibers that enables us to cover any wavelength range from ultraviolet through to near-infrared. You can select your fiber geometry from core sizes of 10 µm to 2.7 mm, and a wide range of circular and non-circular core/cladding fiber designs. Alongside multimode special optical fibers, we also make capillaries and tapers.
- Superior flexibility and product diversity due to strong vertical integration – from the starting material to the finished product
- Customer-specific fiber designs and geometries
