Deep UV Optical Fibers

Engineered for Reliable Performance in Demanding Applications

Deep UV applications place exceptional demands on optical fibers and fiber assemblies. Reliable UV transmission, reduced solarization and long-term stability are essential for consistent system performance. From material selection to fiber geometry, every parameter contributes to the characteristics of the finished fiber. Non-circular core geometries can further support beam homogenization and adaptation to specific light source or detector geometries.

CeramOptec develops and manufactures specialty optical fibers and assemblies engineered to meet these challenges.

FAQs

OPTRAN® UVNS fibers are optimized for long-term UV transmission through a specialized High-OH silica design that reduces solarization during prolonged UV exposure.

OPTRAN® UVNSS fibers build on this design by combining a hydrogen-loaded High-OH silica core with a hermetic carbon layer. The carbon layer helps retain hydrogen within the fiber, supporting improved resistance to solarization during extended operation in demanding Deep UV applications.

The most suitable fiber depends on wavelength, expected UV dose and long-term performance requirements.

Selecting the right Deep UV optical fiber depends on more than wavelength alone. Expected UV exposure, operating conditions, required transmission stability, core diameter, numerical aperture, coating material and connector configuration all influence long-term system performance.

Our engineering team supports customers in selecting the most suitable OPTRAN® UV fiber configuration for laboratory, industrial and OEM applications.

A hermetic carbon layer is recommended for applications requiring maximum resistance to solarization during prolonged Deep UV exposure. UVNSS fibers combine hydrogen loading with a hermetic carbon layer that helps retain hydrogen within the fiber over time, supporting improved long-term UV performance in demanding operating environments.

Hydrogen loading helps stabilize the optical properties of High-OH silica fibers during prolonged Deep UV exposure. In OPTRAN® UVNSS fibers, the hydrogen is retained by a hermetic carbon layer, helping reduce solarization effects over time and supporting consistent optical transmission in demanding UV applications.
