Precise and Durable Light Guidance in the Short-Wave Range
Optical Fibers for
Short-wavelength radiation, high photon energies, and continuous exposure can cause solarization, transmission losses, or premature failure in conventional quartz fibers. In processes such as photopolymerization, disinfection, lithography, or UV spectroscopy, these effects directly impact efficiency, precision, and process reliability.
To meet these challenges, CeramOptec relies on UV-optimized glass qualities, hermetic coatings, and solarization-stable manufacturing processes that maintain stable transmission even under continuous operation. Optran® UV fibers are designed to reliably support critical UV applications, providing precise light guidance, stable performance, and a service life tailored to UV environments.
Typical Applications
- Photopolymerization & UV curing: precise energy delivery for materials and coatings
- UV disinfection & sterilization: efficient light transmission for clinical and industrial use
- Excimer laser systems: stable performance under high UV loads
- Lithography & semiconductor processes: reliable transmission in critical production steps
- UV spectroscopy: high-resolution measurements at short wavelengths
