Non-Circular Core

Armadillo SIA offers non-circular core fibers, available in rectangular, square, octagonal, and various core/clad geometries for applications where precision in the output beam shape and uniformity is crucial.


Armadillo’s non-circular core silica optical fibers exhibit exceptional performance and transmission 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.
