Applications

Primarily selected for applications such as spectroscopy, laser technology, research, photodynamic therapy, andvarious others.

  1. Fiber type - UV = ArmD®️ UV | NIR = ArmD®️ NIR | SRC = ArmD®️ UV-SRC | SHP = ArmD®️ Shaped | NGE = ArmD®️ NIR-Ge | UHC = ArmD®️ UV-HC | NHC = ArmD®️ NIR-HC | MID = ArmD®️ MID-IR | BBD = ArmD®️ Broadband
  2. Standard core / cladding ratios - Core ø (μm) / Cladding ø (μm)
  3. Buffer - H = hard polymer buffer | S = silicone buffer | No information = no buffer
  4. Colour - B = black | BL = blue | W = white | Y = yellow | R = red | G = green | No information = transparent
  5. Jacket material - A = acrylate jacket (no buffer) | F = PFA Fluon®️ | N = nylon jacket (silicone or hard polymer jacket) T= ETFE jacket (silicone or hard polymer buffer) | P = polyimide jacket (no buffer)
  6. Numerical aperture (NA) - 12 = 0.12 | 28 = 0.28 | 22 = 0.22
Other products
ArmD® UV-HC/NIR-HC

ArmD® UV-HC and ArmD® NIR-HC 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.

ArmD® UV-SC/NIR-SC

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® UV-SC and NIR-SC fibers, excelling in UV and MIR transmission, provide full bio-compatibility and cost-effective alternatives to traditional silica fibers.

ArmD® Borosilicate

Borosilicate fibers provide significant advantages across various applications at a lower cost. They excel in light transmission and allow for tight packing in fiber bundles due to their high core-to-clad ratios. Bundle lengths are recommended to exceed no more than 30ft to maintain transmission efficiency.
