Step Index multi mode fiber with pure fused silica core and fluorine doped silica cladding. With a low concentration of hydroxyl groups (OH), this fiber of the Anhydroguide™ series from Fiberguide Industries is suitable for wavelengths in the visible to infrared domain. It is primarily used in photonics applications where individual or bundled large core (> 50μm) multi mode fibers are needed for the transmission of optical energy.
This “AFM” fiber features a low numerical aperture (0.12), resulting in a full acceptance angle of 14°. With a cladding diameter of 140 µm and a silicon buffer coating layer, the minimum bend radius recommended by the supplier is 13 mm (short term) or 25 mm (long term) respectively. The fibers are 100% proof tested using a 4-axis bend method with 100 KPSI. Typical applications are bio-analytical sensing, medical lasers, aerospace/defense, spectroscopy, nuclear plasma sensing or industrial laser systems.
