Optical fiber
Fiberguide Industries
the Anhydroguide™ PCS is the fiber of choice. With an N.A. of 0.37 and a plastic cladding that allows a high
core-to-clad ratio, satisfies those requirements and more. The pure fused silica (SiO2) used in the core of the
Anhydroguide™ fiber is made by reacting silicon tetrachloride (SiCl4) with oxygen (O2) using a plasma arc rather
than an oxy-hydrogen flame. This ensures that the residual hydroxyl concentration (OH) will be low in the core
material resulting in superior infrared transmission as compared with flame prepared silica that is used in the
companion product, Superguide™ which has superior ultraviolet (UV) transmission.
