High Numerical Aperture

Armadillo SIA’s high numerical aperture optical fibers redefine possibilities in applications that rely on superior numerical aperture values. Numerical Aperture (NA) fundamentally influences optical fiber performance by determining its light-gathering ability and the amount of light that can be transmitted efficiently, crucial for achieving exceptional precision in various optical applications.

ArmD® Plus UV WF

As the innovative leader of the fiber optic industry Armadillo is proud to introduce its new line of high NA silica/silica optical fiber – Armd® Plus. Featuring double cladding layers, Plus fibers offer exceptional performance from the deep UV to the MIR. Armd® Plus fibers are an exceptional option for a broad range of applications, from laser delivery to sensing.


ArmD® HUV and ArmD® HWF hard polymer-clad fibers offer high numerical apertures to suit a broad range of applications, from remote illumination to photodynamic therapy. This high-quality fiber is a cost-effective alternative to silica/silica fibers. Explore our range of jacket types and sizes, including customizable options crafted to precisely meet your specifications.


Armadillo’s plastic-clad silica fibers ensure high transmission values across UV to NIR wavelengths, catering to applications ranging from remote illumination to high-power laser delivery and spectroscopy. Our ArmD® PUV and PWF fibers, excelling in UV and MIR transmission, provide full bio-compatibility and cost-effective alternatives to traditional silica fibers.

ArmD® Ultra WFGE

WFGE fibers stand out through maximum numerical aperture (NA) of 0.37. These silica-core fibers excel in performance and offer an expansive spectral range. Armadillo SIA’s WFGE fibers are available in a wide range of core diameter options that can be tailored to your specifications.


ArmD® Borosilicate

Borosilicate fibers offer great advantages for a range of applications at a lower cost. These fibers allow for tight packing within fiber bundles due to their high core-to-clad ratios, providing excellent light transmission.
