Index Matching Gel

Some fiber optic applications such as crimp connectors and fiber optic test kits that use bare fiber, have the two pieces of fiber butt up against each other. At that point there is an air gap between the two fibers. If light were to enter that gap the light would be bent exiting one fiber, and be bent entering the other fiber due to the different indexes of refraction.

The index matching gel helps to reduce the differences between the core and the air gap between the other core.

This index matching gel provides an effective way of reducing Fresnel reflections, and decreasing power loss in connectors and mechanical splices. Easily applied onto connector end faces and inside mechanical splices.

Norland index matching liquid 150 is used to eliminate most of the reflection losses associated with the glass-air interface.

Norland Index Matching Liquid 150 is a low viscosity liquid monomer that can be used as an index matching media for temporary splicing, OTDR testing and other fibre optic applications. This material will not cure and will always remain a liquid.

Norland index matching liquid 150 can also be used to strip cladding modes from a bare fiber or to terminate fibers by dipping the fiber into the liquid.

Unlike silicone-based fluid/gel which is very difficult to remove completely, Norland index matching liquid 150 can be removed simply with acetone.

Other index matching silicone fluids and gels can cause adhesion problems because once they come in to contact with a surface, it is very difficult to remove all traces of the ...
