ArmD™ UV NSS

Silica/silica fiber with hermetic carbon layer

Armadillo’s non-circular core silica optical fibers exhibit exceptional performance and transmission akin to ArmD™ UV/WF fibers with circular core geometry. Their excellent image scrambling and minimal focal ratio degradation make them ideal for astronomy applications. When paired with diode lasers producing square-shaped outputs, these square core fibers offer superior coupling efficiencies compared to circular fibers. In laser applications like surface pre-treatment, their square output beam allows for more uniform material processing, reducing reliance on beam shaping optics.
