ArmD® UV Shaped, ArmD® NIR Shaped Silica Non Circular Core Fiber

Armadillo SIAnon-circular core silica optical fibers display similar outstanding performance and transmission as ArmD^® UV/NIR fibers. Low focal ratio degradation and good image scrambling make it perfect for astronomy applications.

When used with diode lasers, which offer a square-shaped output, the square core fibers provide higher coupling efficiencies than circular fibers.

In laser applications like surface pre-treatment, it is possible to process the material in a uniform way compared to what is possible with a circular beam due to less overlapping. The square output beam decreases the requirement for beam shaping optics.

Three types of standard radii are available for a square shape: r4<10%, 10%<r4<20%, r4 >20%.
