Verrillon’s Ultra-High Solarization-Resistant Fiber performs long-term with exceptional throughput in Deep UV range without solarization effects. This fiber offers many possibilities in a broad range of applications in DUV and radiation environments. The UV darkening resistance is permanent and Verrillon’s VSR fiber does not degrade over time.
