TECHNICAL FAQ
Questions for application planning
How should a refractive-index requirement be specified?
State the wavelength, temperature and whether the value refers to the liquid or cured material.
How do I choose between TZ-136 and TZ-140?
Begin with the fiber architecture and target refractive index. The two products address different application groups and should be evaluated in the intended fiber process.
Does the medical-fiber application description establish device certification?
No. It identifies an intended fiber application. Qualification of the finished device remains application-specific.
