Fused Fiber TAPER
Silica Low OH (300-2400nm) and High OH (190-1200nm) Tapered Fibers
Simplified profile of a fused-end taper
In a fused end taper the “real” taper is very short and can completely be built in a SMA connector. The thin end of this taper is spliced to a standard fiber. Fused-end tapers are more cost effective compared to continuous tapers and can be built with a customized ratio of input diameter to output diameter.
A tapered optical fiber is used to lead a collimated beam with a relatively large diameter into a smaller fiber or to get a better energy density in the immediate vicinity of the fiber output.
We offer fused and tapered optical fibers of the highest quality. All tapered assemblies are available with standard connectors or individually designed ferrules.
