Hard Clad & Silica High NA Fibers
SILICA/hard clad step index low OH fiber (300-2400nm) and high OH fibers (190-1200nm)
These pure fused silica/ Hard Polymer fibers are characterized by high numerical apertures for a wide range of applications from long-range lighting to photodynamic therapy. This high-quality fiber features easy termination without bulb effect and is a cost-effective alternative to quartz/quartz fibers.
We offer a selection of different types and sizes of sleeves as well as individually designed products and sizes according to your specifications.
