Liquid Light Guide, 79 in., 300-650 nm, 0.12 in. Core, 0.59 NA

The 77555 Liquid Light Guide is more efficient and less expensive than a Fused Silica Fiber Bundle and you don’t have to worry about fiber breakage. This 79 inch length UV-VIS version has a 300 to 650 nm range and a 0.59 numerical aperture. It consists of a plastic tube covered by a protective aluminum spiral and covered by a PVC jacket. The inner tube is filled with a proprietary, transparent, anaerobic, non-toxic fluid. The 0.12 inch (3 mm) core is sealed at both ends with polished fused silica or glass windows and protected by an interlocking stainless steel sheathing. It has a 1.6 inch bend radius. This light guide is robust and long-lived in normal use and has 11 mm ferrules on the ends so they fit in any of our Fiber Holders.

High ultraviolet to near-infrared throughput

Liquid light guides provide much greater transmittance than Fused Silica Fiber Bundles, do not have the risk of fiber breakage, and are less expensive. Data shown for 2 meter long light guides.
