Preforms
High-quality preforms form the basis for manufacturing and deploying high-performance special and standard fibers. Thanks to our understanding of the performance parameters required of the final product and the methods of influencing these at each stage of the manufacturing process, we can create the perfect product to match your individual requirements.
Specification of design and configuration of the preform in terms of core profile (step index or gradient index) and doping (e.g. phosphorus) to achieve the desired numerical aperture.
Consideration of the required geometry of the preform for the core and sheath to enable application-specific assembly according to your requirements
